In the meantime, crumble the tofu with a fork and season strongly with the spices. Fry in a pan with a little olive oil. Add the sliced onion. Finally add the chopped tomato. When the tofu and onion are nicely seared, put everything in a bowl.

Now carefully cut off the lid of the peppers, remove the seeds and the rest of the inner workings of the peppers. Now put the filling firmly into the peppers. Then put the lid back on the peppers and place the filled peppers with the lid facing down in boiling tomato sauce. The sauce should be at least 2 cm high in the pot. Simmer for another 30 minutes with the lid closed.
