1. Spread some butter on two slices of the bread (per sandwich) and place them in a (not too hot) griddle pan with the buttered side facing down and let them brown a bit.

2. Top each slice of bread with a slice of cheese. Add 1/4 of the roast beef and 1/4 of the kimchi to one of the slices of bread and close with the second slice of bread that is currently in the pan as well. Fry the sandwich on both sides until the bread is golden brown, crisp, and the cheese has melted – this takes about 3-4 minutes. It’s easier if you put a lid on the pan. Repeat with the remaining bread and toppings.
