Start by cooking the brown rice according to package instructions if it isn’t already prepared. Wash and trim the snap peas, then slice the bell pepper, onion, and shred the carrots. Mix the sauce ingredients (soy sauce, rice vinegar, maple syrup, and cornstarch mixture) in a small bowl and set aside.
In a large skillet or wok, heat 1 tablespoon of sesame oil over medium heat. Add the vegan shrimp and sauté for about 2-3 minutes until they start to brown slightly. Remove the shrimp from the skillet and set aside.
In the same skillet, add the onion, garlic, and ginger. Sauté until fragrant, around 2 minutes. Add the snap peas, bell pepper, and carrots, cooking for about 4-5 minutes until tender-crisp.
Return the vegan shrimp to the skillet along with the cooked brown rice. Pour the sauce mixture over everything and stir well to coat. Cook for an additional 2-3 minutes, allowing the sauce to thicken slightly.
Divide the stir-fry into bowls and garnish with optional chili flakes or a sprinkle of sesame seeds.
