Remove 1 chile from can; reserve remaining chiles and sauce for another use. Remove and discard chile stem and seeds; finely chop chile. Combine chile, mayonnaise, and water in a small bowl. Spread about 1 tablespoon chile mixture evenly over top half of rolls.
Place each chicken breast half between 2 sheets of heavy-duty plastic wrap; pound to 1/2-inch thickness using a meat mallet or rolling pin. Sprinkle each evenly with salt and pepper.
Heat a large nonstick skillet coated with cooking spray over medium-high heat. Add chicken; sauté 3 minutes per side or until done. Remove chicken from pan; top each with a slice of cheese. Arrange coleslaw mix over bottom half of rolls; top with chicken and remaining half. Serve immediately. Serving size: 1 sandwich.
