Preheat your oven to 200 C. Get out a baking dish, 7x11 should work, or even a 9x13 if making a lot of sauce and you have lots of garlic bread on hand.

Heat a large non stick pan with a splash of olive oil and add the garlic and onion, when the onion starts to soften, add the ground beef and break that up and mix in with the onions.

When the beef is cooked through, drain well then stir in the tomato sauce and let that simmer for 10-15 minutes. Remove from heat.

Toast the garlic bread following the shortcut. Once toasted, use your hand and flatten down each slice.

To assemble this concoction. Spread half the sauce on the bottom of the baking dish. Then place slices of toasted and flattened garlic bread in an even layer. Cover that layer with slices of Mozzarella in an even layer. Spread the remaining sauce over the cheese, add another layer of garlic bread, another layer of Mozzarella, then sprinkle Parmesan over the top.

Bake for 40 minutes or until the top is starting to brown. Remove from oven and let rest for 10 minutes, serve.
