Slow Cooker Chicken Quesadillas. Placed 3 chicken breasts, 1 block cream cheese, I used 1 10oz. can of ro-tel, & 1/2 can of reg. diced tomatoes, & I pk. of taco seasoning in my crock pot. Cooked on Low for 6hrs. but can do it on Low for 4-6 or on High for 2-4! When chicken is done take out and shred with two forks and place back in. SPRAY PAN & SPREAD BUTTER (gets brown & crispy) on tortilla cook for 3 min. on each side. ADD LOTS OF CHZ.. Even better the 2nd night. Mas said yum yum yum!
