Cook the chicken breast and coat it evenly with buffalo sauce.
Allow the chicken to cool slightly, then slice it into bite-sized pieces.
Wash and dry the lettuce and vegetables thoroughly.
Chop the Romaine lettuce and place it in a large salad bowl.
Add the cherry tomatoes, cucumber, and red onion.
Top with the buffalo chicken and sprinkle with crumbled blue cheese or shredded cheddar.
Drizzle ranch or blue cheese dressing over the salad.
Toss gently before serving or serve with the dressing on the side.
