Combine beef, garlic, basil, salt and pepper in a bowl and mix with your hands until well combined.
Take tablespoon sized heaps of meat, roll into a meatball shape and then flatten with your hands like a thin hamburger patty. Place a cheese cube in the centre and wrap the meat around, seal and reform back into a meatball. Repeat with remaining meat and cheese.
Place on a tray lined with baking paper and greased with olive oil. Spray meatballs with more olive oil. Bake in the oven at 180C for 15-20 minutes. Remove and serve with hot homemade passata spooned over the top.
