Luckily there are SO MANY vegetarian SBD recipes residing right here!
Some of my favorites are: zucchini and/or eggplant lasagna, butternut squash mac & cheese, veggie chili, pumpkin black bean soup and grilled tofu or vegetarian sausages on a bed of sauteed cabbage (much like the "crack slaw" in the recipes section). Start with the Entrees - Phase 2
section. Many of the recipes are identified as vegetarian, or can easily be substituted with tofu, seitan or fake meat products.
Two things I haven't tried yet but want to:
Greens and Quinoa pie
Butternut Squash Lasagna
Here is something I tried that I loved (from another site): Spinach Ricotta Balls
In general I tend to eat more servings of beans, probably too much nuts and cheese (which can add up quickly). I go back and forth between completely vegetarian and eating some fish. I have also gone vegan several times but right now I am not.
