Cheesy Stuffed Meatloaf Bites

1/2 teaspoon black pepper
1 teaspoon Worcestershire sauce
1/2 cup ketchup
1 tablespoon mustard
1/2 cup grated cheddar cheese
1/4 cup fresh parsley, chopped (additional for garnish)
Preheat your oven to 375°F (190°C). Prepare a baking sheet by lining it with parchment paper.
Mix the meatloaf ingredients: In a large bowl, combine the ground beef, breadcrumbs, milk, egg, onion, garlic, salt, pepper, and Worcestershire sauce. Mix until well combined.
Form the bites: Take a small portion of the meat mixture, flatten it in your hand, place a small amount of cheddar cheese in the center, and then mold the meat around the cheese to form a ball.
