Fry the tofu in oil. medium heat is perfect. Make sure you slice the tofu in squares (like a loaf of bread sliced) when you fry it. you'll make about 15 slices.

fry the tofu until golden brown on both sides.

when the tofu is ready and golden slice it again in cubes or just leave it as if (optional)

Dipping sauce: combine soy sauce, vinegar, pepper and onion powder/onion in a bowl then dunk in fried sliced tofu.

you can eat it over rice or as is! :)
