Caramelized Onion Grilled Cheese Sandwich
My favorite way to order a grilled cheese is with added onions. Sometimes it's a few slices of raw red onion, sometimes it's onions cooked on a flat top griddle before they're added to my sandwich. If it's on the menu, caramelized onions are a definite. Sweet, buttery, almost like an onion jam, they just melt into the cheese. Yum!
