Heat the olive oil in a skillet until shimmery then pan fry the frozen French fries in small batches until golden brown. Place cooked fries on a plate lined with paper towels. Season the cooked fries with rosemary, and salt and pepper to taste.
Separate the cooked fries into small crocks or ramekins loosely. Drizzle the garlic vinaigrette over the fries. Add pizza sauce, shredded pepperonis and shredded mozzarella on top.
Bake the ramekins at 375 F for 5-10 minutes, until the sauce is heated though and the cheese is melted on top. Add parsley on top for a pop of color, as desired. Enjoy!
