Easy Sesame Chicken Salad

Heat oil in a large skillet over medium-high heat. Add chicken, season with salt and pepper, and cook until no longer pink in the center and the juices run clear, about 5 minutes per side. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C). Remove from the heat and set aside to cool.

While chicken is cooling, combine olive oil, vinegar, soy sauce, ginger, brown sugar, garlic, and red pepper in a Mason jar; close lid and shake vigorously until combined.

Chop cooled chicken and place in a bowl with dressing and sesame seeds; toss to combine.

Combine mixed greens, cherry tomatoes, and onion in a large bowl. Mix in dressed chicken and top with mandarin oranges.
