Thanks for the suggestions! I do pretty much all of what you mentioned - I just like having a base protein thing in the fridge that I can throw in there if I haven't cooked any meat/forgot to leave some out for him. He likes scrambled eggs to, though I think hard boiled is his favorite.
No, I haven't read anything about soy in suggies. I did recently see an article regarding carcenogenic health effects in soy diets and hexane used to treat soybeans, but as far as I know tofu and plain soy beans are not treated and don't have high omega six/cancer causing properties. That was just in human diets too, but I'd like to see the link if you have it around.
