I've been lurking for about a month, but since I saw that this was unanswered I registered.
This may be off protocol, but me and my mother are both vegetarians and we both searched around on the web and found that there are a few things good to eat and that work well. My mom has lost a lot on the protocal, and I'm getting there:
1/2 cup Whole grain brown rice and 1 cup stewed beans: Beans are cooked in onions, garlic and a very small amount of tomato sauce.
Sugar free whey or soy protein drinks flavored with stevia. I like to add frozen strawberries so my fruit and meal are one.
Veggie burger pattys topped with either sauerkraut, or onions with garlic and a little hot sauce or whatever on protocol veggie you want on the side.
Last but not least Ezekial bread. Its a complete protein and not quite bread or at least not normal bread. Mom usually has it with two eggs but I only have it with one.
This is what we use to maintain our vegetarian lifestyle and beliefs and it works!
