In mixing bowl, combine diced ham, cream cheese, lime zest, green onions and half of taco seasoning packet contained in soft taco kit. Heat large skillet on medium and spray with cooking spray.

Spread about 1 teaspoon taco sauce onto a flour tortilla and then spread about 1/4 cup ham/cream cheese mixture on top.

Place tortilla-side down onto hot skillet and top with another flour tortilla. Heat about 4 minutes, until bottom of tortilla is browned; spray top of the other tortilla and flip. Cook another 4 minutes and repeat with remaining quesadillas. Cook two at a time if skillet is large enough.

Cut into wedges and top with tomato, cilantro and sour cream and serve.
