Preheat oven to 475 degrees F.

In small pan, cook onion and lime juice with a splash of water for 2-3 minutes. Drain, rinse with cold water and drain again.

In small bowl, mix butter and safflower oil. Set aside.

On one half of each tortilla, arrange 1/10 of the cheese, chilies and mango. Fold tortillas in half. Brush both sides with the butter and oil mixture and place on a cookie sheet. Quesadillas can be prepared to this point one day in advance and refrigerated. To serve, bring to room temperature, and then bake 3-4 minutes (turning once). Cut each into thirds and serve hot.
