I used to live off of these when I was low carbing. They freeze really well. I also occasionally mixed in TVP (texturized vegetable protein) and flax for some extra fiber.
I've learned this recipe from a friend from Mexico. I don't eat menudo, because the tripe or pig's feet made me nauseous. She always celebrated with this soup and I can eat everything in it without being grossed out! It's very delicious and everyone always get seconds or thirds! Don't forget to garnish! I add lots of lemon juice to my bowl and a dash of salt.
