Preheat oven to 375 degrees.
In a large bowl, combine ground beef, half of the Herbes de Provence, the egg, tomato paste and half of the garlic; blend well.
Form mixture into 12 large meatballs then press them into lightly-oiled muffin cups, creating “cupcake liners” made out of beef mixture in the muffin pan.
Add bell pepper, onion, olives, and remaining garlic to each cup in equal portions.
In a small bowl, combine tomato sauce, vinegar and remaining Herbes de Provence; spoon mixture over the veggies then top each pizza cup with Mozzarella cheese; bake for 15 to 20 minutes or until meat is cooked through and cheese is bubbly.
