Prep the shrimp: Pat dry with paper towels.
Season lightly with salt and pepper. Dry shrimp sear better and stay juicy.
Mix the sauce: In a small bowl, combine tamari (or coconut aminos), rice vinegar, sesame oil, red pepper flakes, and a pinch of black pepper. Set aside.
Par-cook the veggies: Heat 1 tablespoon of avocado oil in a large skillet or wok over medium-high heat.
Add broccoli and green beans (or snow peas) first. Stir fry 3–4 minutes until bright and crisp-tender. Add bell pepper and zucchini; cook 2–3 minutes more.
Transfer veggies to a bowl.
Sauté aromatics: In the same pan, add the remaining 1 tablespoon oil and the butter. Add garlic, ginger, and the white parts of the green onions. Cook 30–45 seconds until fragrant.
Do not brown.
Cook the shrimp: Add the shrimp in a single layer. Sear 1–2 minutes per side until just opaque and slightly curled. Avoid overcooking; they’ll finish in the sauce.
Add the sauce: Pour in the sauce and toss.
If you like a thicker glaze, drizzle in the xanthan-oil mixture while tossing to avoid clumps. Simmer 30–60 seconds until glossy.
Return veggies: Add the cooked vegetables back to the pan. Toss to coat and heat through.
Taste and adjust salt, pepper, or vinegar as needed.
Finish and brighten: Zest half a lemon (or lime) over the stir fry and squeeze in a little juice. Sprinkle with the green parts of the onions and sesame seeds.
Meal prep assembly: Spoon cauliflower rice into 4 containers, then top with the shrimp and veggies. Let cool uncovered 10–15 minutes before sealing.
