Let that sandwich grill for another couple minutes each side, flipping until the cheese is gooey and bread is crisp and golden. Keep going till you use up all the stuff and make three sandwiches.

Set bread in a separate skillet, butter side facing down. Build it: drop on two slices of cheddar, slap on a hot beef patty, add two Provolone slices. Slather some sauce on the unbuttered side of a second bread slice and put that on top, sauce facing down.

While you’re cooking the beef, just toss mayo, ketchup, bacon bits, relish, and sugar in a bowl and give it a good mix until smooth.

Swipe butter onto just one side of every slice of bread and set them aside.
