Place chicken strips in a bowl. Sprinkle with cornstarch and toss to coat.
In a small bowl mix together sesame oil, hoisin sauce, soy sauce and 1 clove minced garlic. Pour this mixture over the chicken, turning to coat. Let chicken marinate for 20 minutes.
In a small bowl, mix together sauce ingredients, set aside.
Heat ½ the oil in a large pan or wok over medium high heat. Add the cashews and stir fry for 1 minute, until browned. Watch them closely so they don't burn.
Add the snow peas, celery, remaining garlic, onion, and red bell pepper. Stir-fry for 2-3 minutes.
Remove vegetables from the pan with a slotted spoon and keep warm.
Heat the remaining oil in the pan. Stir fry chicken for 3-4 minutes until cooked through.
Pour sauce into the pan and stir together with the meat until heated through and sauce is thickened.
Return the vegetables and cashews to the pan and add bean sprouts. Stir everything together to coat with the sauce.
Serve over hot steamed rice.
