Chicken, Broccoli, and Lemon Stir-Fry

In a large, shallow bowl, whisk together soy sauce, 3 tablespoons water, vinegar, honey, garlic, and crushed red pepper. Pour half of the mixture into another bowl; reserve. Place chicken in remaining mixture; let marinate 15 minutes.

In a 12-inch nonstick skillet, heat 1/2 tablespoon oil over high heat. Add half the chicken; cook, tossing often, until brown and cooked through, 2 to 3 minutes. Transfer chicken to a plate. Repeat with another 1/2 tablespoon oil and remaining chicken. Wipe skillet with a paper towel.

Heat remaining tablespoon oil in skillet over medium-high heat. Cook broccoli and lemon, tossing often, until broccoli is bright green, about 3 minutes. Add 1/2 cup water; cook until broccoli is tender and lemon is translucent, about 6 minutes.

Add reserved marinade, cornstarch mixture, chicken, and any accumulated juices from plate. Bring to a boil; cook, stirring until thickened, 1 minute. Sprinkle with sesame seeds.
