1. 1. Brown the ground beef in a large skillet over medium-high heat, breaking it apart with a spoon. Drain excess grease. Stir in minced garlic, diced onion (if using), Worcestershire sauce, salt, and pepper. Cook 2-3 minutes until onion softens and garlic is fragrant. Remove from heat and set aside to cool slightly (10-15 minutes).

2. 2. Preheat oven to 375°F (190°C). Line a baking sheet with parchment paper.

3. 3. Open the can of biscuit dough and separate into individual rounds. Gently press or stretch each round thinner if needed.

4. 4. Lay a biscuit round on the prepared baking sheet. Place one slice of cheddar cheese (or a small handful of shredded cheese) in the center. Spoon about 1-2 tablespoons of the cooled meat mixture onto the cheese. Top with another small piece of cheese if desired.

5. 5. Pull the edges of the dough up and over the filling and pinch tightly to seal, forming a neat round ball. Place seam-side down on the baking sheet. Repeat with remaining biscuits and filling.

6. 6. Melt the butter and brush over the tops of each bomb. Sprinkle generously with grated Parmesan cheese.

7. 7. Bake for 15-18 minutes, until golden brown and cooked through. Let cool 1-2 minutes before serving. Garnish with dried parsley if desired.
