In a blender, combine beans and eggs. Blend until smooth, some chunks will remain. Depending on strength of blender, additional water may be useful.
In a bowl, season blended bean mash to taste. Add chopped veggies if desired. Add cumin, chili powder, garlic salt, etc. Add prepared, rehydrated TVP(follow directions on package)- mix thoroughly.
Slowly add flour to bean and TVP mix, stir until mixture is thickened.
To cook, spread a patty sized amount onto a non-stick baking sheet. Bake at 400°F until outside of patty is crispy and browned. Freeze leftover bean mash in small containers. Mash thaws well when using a microwave's defrost feature.
