Season ground beef with basil, oregano, salt, pepper, and red pepper flake (optional). Cook beef and garlic in a skillet over medium heat until no pink remains, about 7-9 minutes. Stir tomato pasta sauce into meat.
Butter one side of bread slices. Spread ricotta on half of slices. Layer in meat sauce and fresh mozzarella.
Grill sandwiches over medium-low heat for 3-5 minutes on each side, or using a panini maker.
