Pizza (or anything!) Rolls

Remember those delicious little Garlic Knots I came up with? I've become a bit obsessed with them, but my kids aren't complaining. I love to make them for a quick bread to go with dinner, but lately I've been stuffing them with various ingredients and giving them to the kids for lunch.
Again, no complaints. Except that time I used spinach. (I ended up eating those, of course.)

Pizza (or anything!) Rolls

1 pizza crust (homemade or store bought)

1/2 cup mozzarella cheese, grated

ham, pepperoni, chopped fresh spinach, etc.
1/2 stick butter, melted
cooking spray

Preheat oven to 400. Spray a standard sized muffin tin with cooking spray. Tear the pizza dough into 12 pieces and flatten each piece into a circle. Stuff with cheese, pepperoni, ham, spinach, etc. Pinch the dough together to completely cover the ingredients. Place roll, seam side down, in the muffin tin. Top generously with melted butter. Bake until puffed and golden brown, about 20-25 minutes.
