Heat 6 tablespoons of olive oil in a large saucepan over high heat. Fry the diced onions and garlic until translucent, about 3-4 min. Add the minced meat and chopped red pepper, fry for 10 min over high heat while stirring continuously. Reduce heat to low and simmer for 5 min.
Stir in the finely chopped chilli peppers and the canned chopped tomatoes with their juice. Add 50 ml tomatoes, a pinch of sugar, and 1-2 tablespoons of oregano. Simmer over low heat for 20 min.
Add the kidney beans (rinsed well with cold water) and simmer over low heat for 15-20 min. Season with salt, freshly ground black pepper, paprika or chili powder, and Tabasco to taste. Add the salt near the end of cooking to prevent beans from hardening.
