A kid friendly dish and delicious for grown-ups too. I used a special pan from Pampered Chef, but a jumbo muffin tin will work here too. I use a frozen pepper stir-fry mix which is essentially green, red and yellow peppers and onions. Using it frozen helps keep the meatloaf moist. This recipe is so versatile. You can customize each meatloaf by adding pepperoni, spinach, mushrooms, olives, bacon, etc. in the middle!
