In a large skillet, cook ground beef over medium heat until brown, using a wooden spoon to break up meat as it cooks. Remove meat from skillet; drain off fat. Keep meat warm.
In the same skillet, heat oil over medium-high heat. Add garlic; cook and stir for 1 minute. Stir in sweet pepper, onion, and the 1/2 teaspoon salt. Cook about 5 minutes or until pepper and onion are softened.
Reduce heat to medium; stir in chocolate, sesame seeds, chili powder, paprika, oregano, cumin, cinnamon, and cayenne pepper. Cook and stir for 1 to 2 minutes or until spices are fragrant (be careful not to burn the mixture).
Remove skillet from heat. Carefully stir in sherry. Return skillet to heat. Add cooked ground beef, the tomato sauce, hominy, and olives. Cook and stir until mixture is combined and thickened. Stir in cilantro. Season to taste with additional kosher salt.
