For the meatless thing...get some veggie burgers and pile some cheese on them. Cheese makes all suspicious foods tasty. Also, they have this meatless "ground beef" which is ok in things like spaghetti sauce and tacos. (I dated a vegetarian. I, sadly, prefer the real thing.)

Ranch dressing and butter are also aids to the vegetable cause, as is a deep fryer.

Of course, all of the above sort of defeat the purpose of eating veggies...maybe sex would work better?

My husband only likes 4 vegetables, hates all lettuce, and is not so into this with exotic tastes. But! He is a converted fan of SmartGround, which has a very tasty taco flavor. And it's perfect for weeknights because the prep work is nil; I call them my 5 Minute Tacos. The regular SmartGround is good in chili, too. He's converted enough that he even suggested getting Boca chicken nuggets.

Bean heavy dishes seem to pass muster on a regular basis too, so sometimes I'll do a bean/vegetable based soup with good bread and he'll be happy.

He's an idiot. Dump him.

Tell him to grow up? 'Picky eater' sounds suspiciously like an excuse for not taking care of his health. I'd love to eat nothing but mashed potatoes and bacon, but I'd also like to live past 40.

Just make what you are going to make and keep something he can heat up or cook quickly if he wants something different or additional. This way you lead by example but he can do the work if he wants something else. It's one night a week, he can suck it up. :)

I think a compromise is in order. Have certain nights of the week when you make an Estaban-friendly dinner, and make extras of it to pack away in the fridge. Make stuff you like on other nights, and make extras of that too. That way you can eat together, both have what you want, and not have to cook two meals every night. Or make stuff you like but also toss some kind of dead animal product on the George Foreman Grill for him. Just because you want to do Meatless Mondays doesn't mean he has to.

I'm lucky in that my husband will eat pretty much whatever's set down in front of him, so I cook whatever I want and he's happy to eat it.

I also have "Fend-for-yourself" nights when things are really busy. I mean, unless a guy is missing all his limbs, he should be able to fix himself a sandwich or reheat leftovers.

I never liked vegetables and was a very picky eater -- I didn't change until I wanted to learn to like new things. For me, I like veggies best when they're still crisp. I still hate veggies when they are cooked until they are mushy. So keep making the veggies, and make extras. If he wants to taste them, he can, and if not, you have leftover veggies, which are a big help in making quick meals.

Or do what I did when my kids were teens. I started cooking just for the two grown-ups in the house. If they didn't want to have it, they could make something on their own, and I kept their favorite groceries stocked as well as ours. When I made everyone's favorites, we had family meal time, and I would introduce a few new things then.

I had one picky eater, who, now that he's graduated from college, will eat almost everything and like it, which is such a huge change from him at 10.

I have one vegetarian daughter, who has been one since 9 years old, of her own volition. She lived on pasta and cheese sandwiches for years. I told her she wasn't allowed to call herself a vegetarian if she didn't actually eat vegetables. She's a legitimate one now, now that she's 20.

Cook for yourself, and he can share, or not.

Oh my god, you're married to my husband! I think he would leave me if I suggested a "meatless Monday". He doesn't even like it if I make a meal with just shrimp, because it's "not enough".

I basically cook what I want, and sometimes make multiple side dishes so I can eat my zucchini and squash and he can eat rice or whatever. But like someone else who commented, I have "fend for yourself" nights.

Cover the veggies in hollandaise!

What about veggie lasagna or pasta dishes? If there's cheese and sauces, maybe the veggies won't scare him so much?

Also, now that farmers market season is getting into full swing, try and whip up some roasted vegetables; squash, red onion (maybe?) asparagus, potatoes, eggplant, and maybe chunks of corn on the cob! I like peppers too, but that may be pushing it for Esteban. Seriously, tossing veggies, olive oil, salt, & balsamic, throw it in a 400 degree oven for 30-40 mins is so easy, and it made my bf a convert - he used to hate all veggies except for lettuce when it's on a burger!

Get a family-friendly vegetarian cookbook—I love "Moosewood Restaurant Cooks at Home"—and have him find the thing that appeals to him the most, even if it doesn't appeal to him very strongly. Sometimes a good recipe description can be persuasive.

This is an extreme example, but I dated a boy for two years who thought a caeser salad counted as his vegetables for the day. He also considered chugging a bottle of juice-like liquid was a smart way to be healthy. Other than that, we only ate pizza, chinese, mexican, and turkish delivery. I went up to 256 pounds and he lost weight due to developing diabetes. I tried every thing I could think of to get us to eat better but he would refuse to eat what I wanted to make. I'm not the best cook but I was sick of not being able to tie my shoes and watching him continue to kill himself with sugar. I eventually overcame my guilt and had to leave him.

This experience didn't turn me into a total health nut. I still eat 99 cent pizza for lunch as opposed to salad more times than not, but I eat significantly better to the tune of 60 pounds lost so far. Now I don't think I could date someone who eats worse than I do. I don't have it in me to try and reprogram the taste palate of an adult.
