Place the ground beef into a large mixing bowl. Add the onion, bell pepper, garlic, mozzarella cheese, Italian seasoning, onion powder, beef bouillon, black pepper, and egg. Mix well. Separate into eight large meatballs.
Make a small indentation in the middle of one meatball. Place one wedge of Laughing Cow cheese. Smooth the meat mixture around the cheese, sealing it in. Repeat for the remaining meatballs.
Slightly flatten each ball into a burger patty. Cook in a grill pan over medium-high heat, about 5-8 minutes on each side, or until nicely browned all around.
Serve with your favorite burger add-ons and ENJOY!
