Preheat oven to 350 degrees. No need to grease the loaf pan.
In a small skillet, heat the peppers, onion and garlic in the olive oil. Cook until tender and translucent, about 7 minutes. Cool.
Combine all ingredients in a large bowl, reserving 4 tablespoons of the BBQ sauce. Portion into 8 roughly equal amounts. Gently press into the mini loaf mold.
Top each mini meatloaf with ½ tablespoon of the remaining BBQ sauce.
Bake for approximately 35 minutes. Remove from oven, let rest for 5 minutes. Pour off the excess fat. Serve hot.
