In a small bowl, combine the drained tuna with mayo, celery, onion, relish, and mustard. Stir it all up until smooth. Sprinkle in salt and pepper, tasting as you go.

If your tortilla feels stiff, pop it onto a plate, cover it with a damp paper towel, and microwave it for 15-20 seconds until bendable.

Spread out a tortilla on your work surface. Add the shredded cheese or cheese slices across half of it but leave an inch or so space along the edges. Spoon the tuna mix over the cheese, keeping the same edge clear.

Bring the left and right edges of the tortilla inward to cover the filling. Lift the closest edge and roll it over the filling. Keep rolling forward while tucking in the sides to make a snug wrap.

Heat some oil in a pan on medium-low. Lay the wrap in the pan with the seam side down. Let it toast for 3-4 minutes, pressing gently with a spatula. Flip it over and cook the other side until crispy and the cheese melts.

Take it out of the pan, slice it in half with a serrated knife if you like, and dig in while it's still nice and melty!
