Preheat oven to 400 degrees.
Put a sheet of parchment paper on a small baking sheet, and scatter the cheese in about a 12x18 rectangle.
Top with the onion rounds, the seasoning, the garlic and finally spread out the calabrese.
Bake 18-20 minutes until browned, then remove and let sit 5 minutes before removing the parchment and slicing.
