Cook your base: Make your rice or quinoa according to package directions. Fluff and set aside.
For a lighter option, use cauliflower rice and warm it just before serving.
Prep the sauce: In a small bowl, whisk soy sauce, water, honey, rice vinegar, sesame oil, garlic, ginger, and sriracha if using. In a separate cup, stir together cornstarch and water to make a slurry.
Sauté the veggies: Heat a large nonstick skillet over medium-high. Add a splash of oil, then the broccoli, peppers, and snap peas.
Cook 4–5 minutes until crisp-tender. Transfer to a plate.
Season and sear the shrimp: Pat shrimp dry. Toss with salt and pepper.
Add 1 tablespoon oil to the skillet and cook shrimp 1–2 minutes per side until just pink. Do this in batches if needed to avoid crowding. Remove to a plate.
Thicken the sauce: Reduce heat to medium.
Pour the teriyaki mixture into the pan and bring to a gentle simmer. Stir in the cornstarch slurry and cook 30–60 seconds until glossy and slightly thickened.
Combine: Return shrimp and veggies to the skillet and toss to coat in the sauce. Cook 1 more minute to warm through.
Avoid overcooking the shrimp.
Assemble meal prep: Divide rice or quinoa among 4–5 containers. Top with shrimp and veggies. Spoon any extra sauce over the top.
Add green onions, sesame seeds, and a squeeze of lime.
