Distribute the grated cheeses over the top of one (1) flour tortilla. Place the Prosciutto slices on top of the cheeses. Place the second flour tortilla shell on top.
Coat a non-stick frying pan with non-stick spray or lightly brush with olive oil. Place on the stove over medium-high heat and brown one side of the quesadilla; then flip and brown the other side until the cheeses are bubbling and tortilla is golden.
Remove from pan and let sit approximately 1 minute for cheese to set up a little.
Cut with a large, sharp knife into four wedges.
Place on individual serving plates and serve.
* An Italian salt-cured and transparent thinly-sliced ham.
