Drain the firm tofu and sponge it with a paper towel. Let stand for 20 minutes.

Meanwhile, peel and crush the garlic cloves.

In a bowl, mix the soy sauce, sesame oil, cayenne pepper, and garlic.

Cut the firm tofu into regular dice.

Heat the sunflower oil in a wok.

Add the cubes of tofu and then brown for 3 minutes on all sides, on medium-high heat.

Add the sauce and sesame seeds. Mix until the sauce is completely absorbed by the tofu.

Serve with sautéed vegetables, if desired.
