In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add diced onion, bell pepper, and minced garlic. Sauté for about 5 minutes until softened.

Increase the heat to medium-high, add ground beef, breaking it apart and cooking for about 8 minutes until browned.

Lower the heat back to medium, stir in tomato sauce, sliced olives, and raisins. Add cumin, oregano, salt, and pepper. Mix thoroughly.

Cover the skillet, reduce heat to low, and let it simmer gently for about 20 minutes.

Taste and adjust seasoning if necessary. Serve warm over white rice, with black beans and fried plantains.
