My favorites:

mixed with the premade ma po tofu mixes from the Asian market (very very high in sodium, but tasty)

extra firm, cut in cubes and fried in butter

coated in cornstarch and deep fried

I also like to buy the pre-fried frozen deep fried pieces (which I can only find at the Asian markets) because no matter how hard I try I'm just not that good at deep-frying tofu.

Wow, after reviewing my list, all of these are incredibly unhealthy!
