Brown the ground beef in a Dutch oven or large pot over medium-high heat until crumbly and no longer pink, about 10 minutes. Pour off any excess grease, then stir in the onion and garlic; cook for 2 minutes before adding the red pepper, green pepper, raisins, olives, tomato paste, water, and cilantro. Bring the mixture to a simmer, then reduce heat to medium-low, cover, and simmer 10 minutes, or until the peppers have cooked to your liking.
