Heat the oven. Preheat oven to 350°F. Spray 6 cups of a muffin tin with cooking spray, being sure to coat each cup thoroughly.
Make the meatloaf mixture. Place the turkey, onion, pepper, salt, oregano, garlic and Worcestershire in a medium mixing bowl and mix until combined. Add egg and panko; continue to mix until all the ingredients are incorporated.
Prepare and cook the muffins. Divide the meatloaf mixture among the 6 muffin cups and bake for 25 minutes, until a meat thermometer registers 160°.
Make the sauce. While the meatloaf muffins are cooking, combine the ketchup and sweet chili sauce in a small mixing bowl.
Top the meatloaf and serve. When the muffins are done, remove from muffin cups and top each with the sweet chili glaze. Serve immediately.
Notes
If saving the meatloaf muffins for later, wait to top them with the sweet chili glaze until you have reheated them and are ready to serve.
