Lightly grill the whole wheat tortilla on both sides in a dry pan.

Crack an egg onto the tortilla and gently spread it.

Add the drained gochujang tuna on top of the egg. The original recipe also includes 1/4 sliced onion at this step (optional).

Sprinkle a generous amount of mozzarella cheese over the tuna.

Fold the tortilla in half and cook until the cheese is melted and the outside is golden brown.
