In a large skillet, heat the olive oil over medium heat.

Add the diced onions and green peppers, cooking until softened, about 5 minutes.

Add the ground beef to the skillet. Cook until browned, breaking it apart with your spatula, about 7-10 minutes.

If there is excess fat in the skillet, drain it carefully.

Add the sugar-free ketchup, Worcestershire sauce, garlic powder, onion powder, and smoked paprika to the meat mixture. Stir well to combine.

Reduce the heat to low and let the mixture simmer for 10 minutes, stirring occasionally.

After simmering, taste the mixture and add salt and pepper as needed.

Serve the mixture on your choice of low-carb base, like cauliflower rice or in lettuce wraps.
