1. Rinse the shrimp with cold water and pat dry. 2. Combine the marinade ingredients in a bowl. Add the shrimp and marinate in the refrigerator for 30 minutes. 3. Lightly coat a nonstick wok or frying pan with cooking spray and place over medium heat. Reserving the marinade, add the shrimp and sauté until they just turn pink (2 to 3 minutes). Transfer to a bowl. 4. Add the snow peas, onion and ginger to the pan and stir-fry for 1 to 2 minute. 5. Add the reserved marinade and soy sauce to the pan along with the cooked shrimp. Mix the ingredients well and continue to cook until the most of the sauce is absorbed (1 to 2 minutes). 6. Transfer to a serving bowl, sprinkle with sesame oil and serve hot. 7. Serve with rice.
