Tuna Brioche Sandwich

We mix the drained tuna with chopped onion, corn, chopped hot pepper, diced pickled cucumbers, and shredded red cabbage in a large bowl.

We add mayonnaise, mustard, lemon juice, a pinch of salt, and black pepper, then mix well until all ingredients are combined.

We lightly toast the brioche bread in a pan or toaster, place a slice of cheddar cheese on it, add the tuna mixture on top, and cover with the other half of the bun.

We serve the sandwich immediately, either warm or at room temperature.
