This grilled macaroni and cheese sandwich with braised short ribs is the ultimate comfort food. Tender braised short ribs are piled high on a bed of creamy macaroni and cheese, then sandwiched between two slices of buttery grilled bread. The combination of the rich, savory short ribs and the gooey, cheesy macaroni is a match made in heaven. This indulgent sandwich is perfect for a cozy night in or a decadent lunchtime treat.
