Start by finely dicing the onion, bell pepper, carrot, and celery. These veggies will add flavor and nutrition to your meatloaf muffins.
In a large mixing bowl, combine the ground turkey, breadcrumbs, diced vegetables, milk, egg, ketchup
Use your hands to mix all the ingredients together until well combined. Be careful not to overmix; just ensure everything is evenly distributed.
Divide the turkey mixture into muffin tin cups. This recipe should make about 12 meatloaf muffins.
Shape the portions into muffin-like shapes. Top each muffin with an extra dollop of ketchup for added flavor
Preheat your oven to 375°F (190°C). Place the muffin tin in the oven and bake for about 25-30 minutes
To ensure they're done, use a meat thermometer. The internal temperature should reach 165°F (74°C).
