Hidden Cheeseburger

1 lb ground beef
2 sm dill pickles, minced
1 sm onion, minced
2 TBS grated Parmesan cheese
1 TBS mayonnaise
1 TBS ketchup
1 tsp minced garlic
salt and pepper to taste
2 TBS olive oil
2 TBS flour
1 lb frozen bread dough, thawed
8 slices cheese
1 TBS melted butter

Combine the ground beef, pickles, onion, Parmesan cheese, mayonnaise, ketchup, garlic, salt, and pepper in a bowl. Form the mixture into 4 patties. Heat the olive oil in a skillet over medium heat. Cook the hamburger patties in the hot oil until the burgers are cooked to your desired degree of doneness, 8 to 10 minutes for well done. Line a baking sheet with parchment paper, and set aside. Cover a flat surface with the flour. Divide the bread dough into 4 even pieces; roll each piece into a flattened rectangle on the floured surface at least twice the size of the cheese slices. Place one slice of cheese on each piece of dough; top each with one of the cooked patties and another slice of cheese. Fold the dough over the top of the meat and cheese. Pinch the dough around the edges to seal completely. Arrange on the prepared baking sheet with the seam side facing downward. Brush the tops with the melted butter; move to a warm area and allow to rise for 20 minutes. Preheat oven to 425F. Bake in the preheated oven until the bread has browned, about 20 minutes.
