Soak the beans overnight in 1 litre of cold water. Boil the beans in the soaking water, cover and simmer for about 1 hour. Clean the chillies, cut lengthwise, remove seeds and wash. Finely dice one chili. Peel garlic and dice finely. Clean, wash and chop the peppers and zucchini. Wash the fillets, dab dry and dice finely. Grate cheese. Add 1 teaspoon salt and whole chilli to the beans.
Simmer open for another 15 minutes. Peel and finely dice the onions. Heat the lard in a large pan. Fry half of the onions in it. Remove the chilli from the beans. Add half of the beans together with the cooking water to the onions in the pan and mash them with a potato masher. Gradually add the remaining beans and liquid and mash into a coarse puree. Stir and heat up at medium temperature until the puree becomes dry. Season to taste with salt and pepper. Heat the oil in a frying pan. Fry the fillet for approx. 4 minutes while turning. Add vegetables, rest onions, garlic and chili cubes. Fry for another 3 minutes. Season filling with salt and pepper. Line baking tray with baking paper. Spread the filling over one half of each tortilla. Sprinkle with half cheese.

Fold the tortillas over and pin them down with 1 wooden skewer each if necessary. Put them on the baking tray. Melt butter. Spread the tortillas with it and sprinkle with the rest of the cheese. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for about 8 minutes. Arrange everything. Garnish bean purée with parsley strips and chilli. Sour cream tastes good with it
