Crunchy Tuna Wrap

In a bowl, combine the tuna, mayonnaise, mustard, onion, corn, tortilla chips and mix. Arrange the large tortillas on work surface; spread 1/4 of the mixture on each tortilla, leaving small border at either end; drizzle little grated mozzarella, place the smaller tortillas on top and tightly fold edges of large tortillas toward the center, creating pleats. Heat a non-stick frying pan (without adding cooking fat), place the tortilla seam-side down, and cook, flipping once, until tortilla is golden, about 5 minutes per side. You can also bake the tortillas in the oven, at 200^oC for about 15 minutes or in the toaster. Cut in half and serve with green salad on the side.
