10sweet rolls, cut in half (such as King's Hawaiian)
Instructions
Preheat oven to 425 degrees. Line a baking sheet with foil, set aside.
In a bowl, combine the meat, panko, egg, parmesan, parsley, ketchup, milk, and salt. Roll into 10 evenly-sized balls and place on baking sheet. Press down slightly to flatten to a 1 ½ inch thickness. Bake for 15 minutes.
Remove from oven and top with marinara sauce and a cheese. Broil for 2-3 minutes, until cheese is melted and bubbly. Sandwich in buns and serve warm.
Notes
Make-ahead tip: Prepare the meat and roll into balls up to a day in advance then bake before serving. You can also freeze the cooked meatballs and reheat before serving.
