Tofu
Tempeh
Seitan (warning: not for those with gluten allergies)
Textured Vegetable Protein (TVP)
Morningstar Farms and Garden Gourmet are two kosher brands that make delicious pseudo-meats. You can find their “schnitzel”, “hamburger”, and “sausage” products etc in the frozen foods section of any supermarket.
