Kimchi Tuna Melt

Inspired by an item from the Kogi truck, I made my own version of their Kimchi Tuna Melt. Mine was on thick Japanese white toast with a simple tuna salad. The cheese is a Kraft American cheese (not too fancy, I know, but it melts so well). The kimchi relish I made is chopped kimchi, a dash of brown sugar (balances out the sour of the kimchi), and sesame oil. Grill the bread on a skillet with butter.
