The best part of a dish this simple is that there's really no set recipe to worry about sticking to - it comes together with whatever you have on hand in your refrigerator. Serving up something so simple, though, means that you've got to keep one big factor in mind: texture. Think about how to incorporate things that are creamy, crispy, crumbly, and moist to keep a dinner with only a few ingredients both interesting and satisfying.
In a small bowl, mix together the cheese and mayonnaise. Season the chicken breasts with salt and pepper and arrange them on a baking sheet. Evenly divide the cheese mixture between the chicken, spreading it out to cover the surface of the meat. Bake the chicken until the cheese is golden brown and chicken is cooked through, 15 to 17 minutes.
To serve, slice the chicken and arrange it over the chopped salad.
