Lay the tortilla on a work surface, spread it with the mustard. Lay the ham on top to cover the whole tortilla. On one side of the tortilla lay the peppers, sharp cheddar and sprinkle the chopped green onion and jalepeno over. Fold the tortilla in half. Have the grill very hot, lay the folded quesadilla on the grill and press it down. Grill for about 6 or 8 minutes until the cheese melts, then flip it and grill the other side. Use a panni press if available and no need to flip.
Remove to plate and slice in half. Spread half the salsa on each tortilla half.
