Black-Jack Chicken Quesadillas

This is a great appetizer or a quick dinner with a spicy/sweet flavor combination.  

Black-Jack Chicken Quesadillas

1/3 cup blackberry preserves
1 chipotle from canned chipotles in adobo, pressed in a garlic press or chopped (with seeds removed)
3 Tbsp balsamic vinegar
2 Tbsp fresh cilantro, chopped (or Trader Joe’s sells frozen cubes of cilantro- use 3-4)
1 clove garlic, minced
1/8 tsp black pepper
1 cup cooked chicken breast, cut into small chunks or shredded
1/2 cup diced onions
2 cups shredded Monterey Jack cheese
10 (6 inch) flour or corn tortillas

In a medium saucepan, whisk together blackberry preserves, chipotle in adobo, balsamic vinegar, cilantro, garlic and black pepper. Turn heat to medium and heat just until mixture begins to bubble. Remove from heat. Add chicken to saucepan and toss to coat chicken in berry mixture. Toss onions and cheese together.
If using flour tortillas, spoon 2 tablespoons cheese/onion mixture evenly down center of each tortilla. Spoon chicken and berry mixture over cheese, dividing equally among tortillas. Fold tortillas over to make quesadillas.
If using corn tortillas, spread berry chicken mixture on one corn tortilla and top with 2 tablespoons cheese/onion mixture, leaving room at the edges for the mixture to spread. Top with another corn tortilla and carefully transfer to pan (sometimes it’s easier to build the quesadilla in the pan).
Heat a non-stick skillet or griddle to medium and cook quesadillas for 3-4 minutes each time or until cheese is melted and edges are golden brown. Cut each tortilla with a pizza cutter into triangles.
