How to make
Boil the beans and discard the first water in which you have poured a little soda. Boil them, but make sure they're not completely cooked, so the beans stay whole.
In a deep frying pan or saucepan fry the onion and minced meat, add the tomatoes that have been mashed or finely chopped. If you do not have tomatoes, you can use tomato puree.
Fry the minced meat well and season it with spices of your choice. Finally, add the beans, stir and fill the peppers, that have been cleaned of their seeds.
Pour water into the baking pan. but not that much that it covers the peppers. Season them with salt and bake them in the oven until they're fully cooked.
