Add butter to a large skillet or dutch oven over medium high heat.
Add ground beef, onion, and garlic and cook until brown. If using grass fed beef there shouldn’t be much leftover grease.
Add ketchup, coconut sugar, chili pepper, dry mustard, and water.
Stir to combine and simmer for 15 minutes, adding salt and pepper to taste.
Add Worcestershire if desired. Taste and adjust seasonings as needed.
Serve over gluten free bread. You can get creative and put over veggies, or atop baked sweet potatoes.
