Pizza Grilled Cheese

¼ cup butter, softened 
1/8 teaspoon garlic powder (or more to taste) 
1 teaspoon oregano
8 slices of bread  
1 package sliced pepperoni 
1-1 1/2 cups mozzarella cheese, shredded 
Pizza sauce (for dipping)

In a small bowl, mix together butter, garlic powder and oregano.  Smooth onto one side of each piece of bread.  Heat a frying pan over medium heat, and place buttered bread buttered-side down.  Top with a handful of mozzarella cheese (approximately 1/4 cup), and top with slices of pepperoni.  Place another piece of bread on top, with the garlic butter facing out.  I like to place a lid on top to help melt the cheese.  After a couple minutes when the bread is golden brown, flip and cook the other side until golden brown.  Repeat with all sandwiches, and serve with a side of pizza sauce for dipping.
