Preheat the grill to medium-high heat.
Season the chicken breasts with salt and pepper, then brush with olive oil.
Grill the chicken for about 6-7 minutes per side, or until fully cooked (internal temperature should reach 165°F).
Remove the chicken from the grill and let it rest for 5 minutes. After resting, slice the chicken into strips.
In a bowl, toss the salad greens, cherry tomatoes, cucumber, red onion, and shredded carrots together.
Drizzle the salad with ranch dressing and toss to coat evenly.
Top the salad with the sliced grilled chicken and sprinkle with blue cheese crumbles.
Drizzle additional buffalo sauce over the top if desired, and serve immediately.
