I have tried tempeh. I liked using seitan more, and I continued with that. Now I am actually generally using jackfruit, now that I know where I will get it, and it would still be there. I wonder about getting enough variety, still. I do have a sandwich and a bean burrito each day generally, and they are basically the same. For cooked meals I alternate between potato, quinoa, and whole grain noodle. Is this enough variety, one cooked meal each day? I use vegetables cut up in them still, with the hummus, medium salsa, and seasonings.
