Here's a delicious, healthy recipe for vegetables that is quick, easy, and involves no cooking or baking that will give you tons of energy and nutrition: green juice! All you need is a juicer (such as the Omega 8004 like I have), a bunch of your favorite green veggies, and about 10 minutes of time. It's a great idea to have it for breakfast because it's a natural energizer and mood booster, so it sets you up for a great, happy day. (Jump to the bottom of the post for the video recipe)
By Dr. Jill Hechtman M.D. OB/GYN explains, in a somewhat cheesy and lacking video, that it is completely safe to have a vegetarian diet while pregnant. And since she doesn't mentioned that dairy is necessary, I assume that she believes veganism is OK too. Her main piece of advice is to make sure you get enough protein and nutrients, recommending beans, vegetables, pre-natal vitamins, and extra supplements. She says, "the [food] pyramid is essentially the same, just take out the meat and add your proteins that will help keep your diet balanced"
