Tofu, cut in cubes
Noodles (rice or hokkien or whatever)
Vegies (eg broccoli, Asian greens like choy sum, green beans, whatever)
Vegetable stock cube (or soya sauce or salt)
Grated ginger (optional)
Boil in a saucepan until everything's cooked through. You might need to add some of the vegies at the end so they're not overcooked. Firm tofu works better than softer tofu for this recipe.
I rarely eat tofu these days though - seems to upset my innards, unfortunately.
