Now this is a grilled cheese sandwich.
Spread butter on all sides of the bread. On the sides of the bread that are facing up, sprinkle granulated garlic on top of the butter. On 3 slices of bread, top the garlic butter with half of the cheddar and mozzarella cheese.
Cut the length of the roasted asparagus so that each spear is equal to the length of the bread. Lay the spears of asparagus on top of the shredded cheese. Top the asparagus with the remaining cheddar and mozzarella cheese.
