In a large bowl, combine chopped chicken, bell peppers,jalapeno, red onion, spinach, salt, pepper, cumin, paprika,chili powder, greek yogurt, bbq sauce and cheese (note*if you like a really cheesy quesadilla add ¼ cup additional cheese)!. Mix well.
To a large pan over medium heat, add one tortilla. Warm each side of the tortilla for about 30 seconds before brushing a thin layer of oil on one side. Flip the tortilla and spread 1.5 cups of filling to half of the tortilla. Fold the other half of the tortilla over the filling, brush the top of the quesadilla with a thin layer of oil and allow to cook for about 3-5 minutes. Carefully flip the quesadilla and allow the other side to cook for about 3-5 minutes.
Allow to cool for about 5 minutes before slicing into 4 equal triangles.
Repeat with the remaining 3 tortillas.
