- Whisk together ingredients for sauce in a saucepan until cornstarch is dissolved. Heat over medium-low heat until simmering. Continue to simmer for 3-5 minutes, until the sauce has thickened. Pour sauce into a small bowl to cool slightly for 15 minutes.
- Preheat oven to 425°F and use cooking spray to lightly grease a medium baking sheet lined with foil. Add snap peas, bell pepper and onion to one half of the pan and drizzle with ¼ cup of sauce. Toss to coat. Add shrimp to the other half of pan and drizzle with ¼ cup of sauce. Bake for 15 minutes, until shrimp is pink and vegetables are tender.
- Remove from oven and sprinkle with sesame seeds and green onion. Serve shrimp and vegetables over rice. Drizzle with remaining sauce.
