Grilled Meatloaf Sandwich

"These Grilled Meatloaf Sandwiches have been a favorite of ours for as long as I can remember. Sometimes I think we make meatloaf just for the sandwiches. Don’t skip the Chipotle ketchup as it complements the sandwich so well. These Grilled Meatloaf Sandwiches take leftovers to a whole new level. Now add my chipotle ketchup and you have yourself an exceptionally tasty treat. I love to serve them with Crispy Onion Rings and Grandma’s Creamy Dill Pickle Potato Salad. You can use any kind of meatloaf made from beef, turkey, pork, vegetarian or a combination. "
