Spread 1/2 teaspoon of Dijon mustard on each tortilla.
Top two of the tortillas with ham, apple slices, and cheddar cheese, then top with remaining tortillas.
Preheat griddle or large skillet to medium-high heat. Grease with olive or canola oil. I do this by pouring approximately a tablespoon of oil onto my skillet/griddle, and then spreading it out lightly with a paper towel, so there is just a thin layer of oil on the surface.
Place on greased griddle.
Cook for 3-4 minutes, and then flip. Cook another 3 -4 minutes, until cheese is melted.
