Heat olive oil in a large skillet over medium heat. Add onions and garlic, sauté until onions are translucent.

Add ground beef to the skillet. Cook, breaking it apart with a spoon, until browned.

Stir in tomatoes, olives, raisins, capers, cumin, oregano, salt, and pepper. Add water or broth and bring to a simmer.

Reduce heat and simmer for 20 minutes, or until most of the liquid has been absorbed and the flavors meld together.
