Make the sauce: In a small bowl, whisk soy sauce, oyster sauce, rice vinegar, honey, sesame oil, red pepper flakes, water, and cornstarch until smooth. Set aside near the stove.
Prep the shrimp: Pat shrimp dry with paper towels and season lightly with salt and pepper.
Dry shrimp sear better and stay juicy.
Heat the pan: Place a large skillet or wok over medium-high heat. Add 1 tablespoon oil and swirl to coat.
Cook the shrimp: Add shrimp in a single layer. Cook 1–2 minutes per side until just pink and curled.
Transfer to a plate. Do not overcook.
Stir-fry the vegetables: Add remaining 1 tablespoon oil to the pan. Add broccoli and carrots first.
Stir-fry 2 minutes. Add bell pepper, snap peas, and the white parts of the green onions. Stir-fry 2–3 minutes more until crisp-tender.
Add aromatics: Push veggies to the edges.
Add garlic and ginger to the center and cook 30 seconds, stirring, until fragrant. Mix into the vegetables.
Sauce it up: Whisk the sauce again and pour it into the pan. Stir constantly for 30–60 seconds until the sauce thickens and turns glossy.
Finish with shrimp: Return shrimp to the pan and toss to coat.
Warm through for 30 seconds. Remove from heat.
Garnish and serve: Sprinkle with sesame seeds and the green parts of the green onions. Serve over rice or noodles with lime wedges if you like.
