Costco's Meatball Sandwich Tastes Best When You Heat It Up Correctly
BY DEB KAVIS
Get ready to up your meatball sandwich game with the newest addition to Costco's deli offerings: the Beef and Pork Meatball Sandwich with Marinara.
This jumbo-sized sub boasts a bevy of pork and beef meatballs, marinara sauce, provolone, and Parmesan cheese between two slices of artisan hearth bread.
Due to its massive size, you'll want to forgo the air fryer in favor of oven-baking. We recommend simply covering it and popping it into a preheated oven until it's warm.
Then, uncover and pop it under the broiler for an extra gooey consistency on the provolone for a minute or two before digging in.
