Step 1

In a small bowl, mix together the ketchup, apricot jam, chipotles, and mayonnaise.

Step 2

In a large nonstick skillet over medium-high heat, cook the meatloaf slices until heated through and starting to get crisp, about 2 to 3 minutes.

Step 3

Flip the slices of meatloaf, divvy the cheese between them, and cook until the cheese begins to melt, 2 to 3 minutes more. Slide the meatloaf slices onto a plate.

Step 4

Add the bread to the skillet and cook until just toasted.

Step 5

Spread about 1 1/2 tablespoons of the sauce on two slices of the toasted bread. Top each slice with arugula, half of the cheese-topped meatloaf, and the final slice of bread.
