Ok so this is an easy cheat recipe but it’s good and fast. I like meatball subs....but I use frozen meatballs. So you need a bag of frozen meatballs and microwave 4 of them per package directions. Then toast a hotdog bun or use it plain with the four meatballs. Add a broken in half slice of provolone to the bun and microwave until it melts usually 8-10 seconds. Add some jarred marinara sauce, whatever variety you like and enjoy!
