Preheat your oven to 350°F (175°C).
In a large bowl, combine ground turkey, breadcrumbs, onion, bell pepper, and garlic.
In a separate bowl, whisk together the egg, milk, ketchup, Worcestershire sauce, salt, and pepper.
Pour the wet mixture into the turkey mixture and mix until just combined.
Shape the mixture into a loaf and place it in a baking dish.
Spread additional ketchup on top for a glaze.
Bake in the preheated oven for 60 minutes or until the internal temperature reaches 165°F (75°C).
Let the meatloaf rest for 10 minutes before slicing.
Serve warm with your favorite sides.
Enjoy your hearty turkey meatloaf!
