Cook the chicken. Season the chicken breasts generously with salt and pepper. Heat the oil in a sauté pan over medium-high heat. Cook the chicken for 4-5 minutes per side until cooked through and no longer pink inside. Transfer the chicken to a clean cutting board and let it rest for 5 minutes, then dice into small pieces.
Prepare the vinaigrette. Meanwhile, prepare the vinaigrette by whisking all of the ingredients together in a bowl (or shaking vigorously in a sealed jar) until emulsified.
Combine. Combine the diced chicken and remaining salad ingredients in a large bowl. Drizzle with the vinaigrette and toss until evenly combined.
Serve. Serve immediately and enjoy!
