Start by taking two thick slices of your favorite bread, spread a thin layer of butter or mayonnaise evenly on one side of each slice.

Turn the slices of bread buttered-side down, layer cheese on both slices, then distribute kimchi on one slice.

Bring the two halves together, gently press down to meld the flavors, and secure with a toothpick if needed.

Place the assembled sandwich in the preheated air fryer for 8 minutes until golden brown and crispy, or cook on a skillet for about 4-5 minutes on each side.

Remove the sandwich, let it sit for a minute, slice in half, and serve warm with pickled vegetables.
