Meanwhile, in a medium sauté pan, heat 1 tablespoon of the olive oil over medium heat. Salt and pepper the beef. Add the seasoned ground beef to the pan, and sauté until all of its liquid is evaporated and the beef begins to brown slightly. Let cool briefly, and chop the cooked beef so that there are no large chunks of meat. In another medium sauté pan over medium heat, add the remaining 2 tablespoons olive oil, and sauté the onion, pepper and garlic together in the oil.
