Low Carb, high protein foods

[jchiplinsky]

With all the carbs I have been eating, it has made me really bloated and weighed down.
I would use more tofu, but I can't seem to find any that is cheap enough.

I was wandering what your advice would be for what food I should use more of to make my meals more filling, not so expensive, with not too many carbohydrates? (I don't ask for much, I know :P)

Thank you in advance for all of your wonderful ideas!
