Heat a saucepan over medium heat. Melt the butter, and then stir in the garlic. Cook for 1 to 2 minutes, or until the garlic is lightly browned.
Stir in the hot sauce, Worcestershire sauce and brown sugar. Reduce heat to low and simmer the sauce for about 3 to 5 minutes or until thickened. Set aside.
Heat a large skillet over medium-high heat. Add the oil and then stir in the chicken. Cook for 2 minutes or until the chicken is lightly browned. Stir in the onion and bell pepper and cook with the chicken for 3 to 5 minutes or until the vegetables are tender.
Stir in the buffalo sauce and cook for another 2 minutes or until everything is well combined and heated through. Season with salt and pepper to taste. Serve with tortillas and optional toppings.
