Step 1

Place the chicken breasts into the dish of a slow cooker. Pour the buffalo sauce over the chicken, and stir to combine. Cover and cook on low for 7 to 8 hours or high for 4 to 5 hours.

Step 2

Once the chicken is cooked through, shred the meat with two forks and toss to coat with the sauce.

Step 3

Place the tortillas on a flat surface. Top 4 tortillas with the chicken, Cheddar cheese, and blue cheese. Assemble the quesadillas.

Step 4

In a large skillet, melt butter over medium-high heat. One at a time, place the quesadillas into the skillet and grill for 3 minutes or until the cheese begins to melt. Flip and grill for another 3 minutes or until the cheese is completely melted. Remove from the skillet and repeat with remaining quesadillas.

Step 5

Slice and serve Ranch or Blue cheese dressing.
