Combine the meatloaf fixings: Mix the ground beef, breadcrumbs, Worcestershire sauce, milk, egg, onion, garlic, salt, and pepper in a big bowl. Beat until everything is blended.
Cut the meat into bite-sized pieces by taking a little bit of the mixture, pressing it down with your palm, placing a little cheddar cheese in the middle, and shaping the pork around the cheese to make a ball. Arrange the baking sheet in the preheated oven. Proceed with the leftover meat and cheese in the same way.
Glaze should be prepared: Combine the mustard and ketchup in a small dish. Distribute this mixture evenly over the surface of every mouthful of meatloaf.
After the meatloaf bits have caramelized on top and cooked through, bake them for 25 to 30 minutes on a baking sheet.
Before serving, garnish with extra chopped parsley.
Savor it!
