I am in the same boat--is your wife with Wisdom midwifery? I buy a lot of frozen greens (spinach, collards, and my favorite, mixed leafy greens from WF) because they are cleaned and ready to throw into whatever I am cooking. I scramble them into eggs a lot, add them to soup, or to mixed vegetable pasta or curries.

I make all kinds of versions of what I call "greens and beans." Use a base of onions, garlic, carrots, celery (any combo) and whatever herbs you like. Add greens of choice, and beans (garbanzo, cannellini, red kidney, etc.). I usually add some type of broth or white wine and let them all simmer. Really good.

You can also give them in supplement form...superfoods are the way to go. Just a few grams of this can equal a full serving of vegetables. I take this and give it to my children because they are not a real fan of veggies yet. It does the trick and keeps their PH levels balanced.

I like lentil soups and stews with spinach or chard.

There are a lot of great ideas here. Just wanted to add a couple:

Spinach Lasanga
Kale, Italian sausage, and bean soup (double folate!)
kale pesto! Really! It's SO good!
And these 'green" tacos are incredible:

and this casserole is to die for:

if you like Ethiopian food, they make nice greens (spicy) in the restaurants

Pasta, soups, chili

With bulgur or quinoa

I eat alot of greens, but really hated them when I was pregnant.

I also made a raw kale salad that was delicious, believe it or not. Get it from the farmer's market and massage it to tenderize.

I've also been trying to eat more and find that it's easiest to just throw a handful of spinach into just about everything I eat. For example, last night I made a pasta dish and put a ton of spinach in the bottom of my bowl and just threw the hot pasta on top.

Google Kale Chips, they were on all the food blogs a couple of years ago.

We eat them in frittatas, soups, chili, and vegetable enchiladas or tacos. I also throw raw greens into salads with a mix of lettuces and herbs.

Spinach, kale, and chard are all great in frittatas. Also, here's a good kale and quinoa recipe from food52: http://www.food52.com/recipes/2434_one_pot_kale_and_quinoa_pilaf

My new favorite cookbook is Love Soup, by Anna Thomas. She has a recipe for "green soup" that is made with kale and chard that is so delicious. In fact, she has a whole chapter on different green soups, but the original is my favorite. Wished I had had this book during my pregnancies. Highly highly recommend this cookbook.

You can add chopped spinach to a bunch of dishes; omelette, chili, any kind of stew or casserole. I add kale or chard to my chili. I know folks who swear by roasted kale, although I'm not a fan--but you might look for kale chips at the health food store.

Also, is this primarily for folic acid? There is also folate in a lot of legumes--lentils, navy beans, black beans:

This kale doesn't look great when you cook it down, but it tastes really good.

DW is pregnant and supposed to eat a lot of leafy greens like spinach and kale per her midwife. Besides spinach salads and sauted greens, what are some other ways we could eat greens? DW doesn't like collards.
