Heat the olive oil in a pan over medium heat. Add the diced onion, bell pepper, and garlic, and sauté for about 5 minutes, until softened and fragrant.

Add the ground beef and cook, breaking it up as it browns, until no pink remains.

Season the beef with a pinch of garlic salt, adobo seasoning, salt, and black pepper. Stir well to evenly coat the meat.

Add fresh thyme, oregano, and basil, or dried herbs if fresh herbs are not available. Stir everything together and cook for another 2 to 3 minutes to let the flavors bloom.

Pour in the tomato sauce, reduce the heat to medium-low, and let the sauce simmer for 10 to 12 minutes, stirring occasionally.

Taste and adjust seasoning if needed, then serve over your pasta of choice.
