In a large bowl, mix the ground beef with the salt, granulated garlic, black pepper, cumin, oregano and Sazón until evenly seasoned.
Heat the olive oil in a large skillet over medium heat. Add the onion and the green, red and yellow peppers, and cook for 5 to 6 minutes until soft. Stir in the garlic and cook 1 minute more.
Add the seasoned beef and raise the heat to medium-high. Break it up with a spoon and cook for 8 to 10 minutes, until browned with no pink left, to an internal temperature of 160°F.
Stir in the tomato sauce, vinegar and olives. Lower the heat, cover, and simmer for 10 to 15 minutes, stirring now and then.
Taste and adjust the salt and vinegar, then stir in the cilantro. Serve with white rice and black beans, or save it for stuffed potatoes, tacos and empanadas.
Notes
Leftovers keep 4 days in the fridge or 3 months in the freezer. Use them for papas rellenas, tacos, stuffed peppers and empanadas.
