Cook the peppers until soft, peel and seed them, and press the flesh through a sieve.
Heat the olive oil, add the garlic, marjoram and a pinch of salt, then add the pepper pulp and simmer over low heat.
Season the onions with salt, pepper and marjoram, and let them stand in a little vinegar.
Strain the sauce and return it to the heat.
Dip a tortilla in the sauce, place it on a plate, spread it with a teaspoon of drained onion and grated cheese, then put two olives, two raisins and a tablespoon of chili on it.
Roll it up and sprinkle the top with onion and cheese. Continue the same way with the other tortillas.
Pour the remaining sauce over them and garnish with olives.
