Cook the noodles: Boil according to package directions until just tender. Drain and rinse briefly under cool water to stop cooking.
Toss with a few drops of oil to prevent sticking and set aside.
Prep the shrimp: Pat shrimp dry with paper towels. Season lightly with salt and pepper. Toss with 1 tablespoon cornstarch until evenly coated.
Make the sauce: In a small bowl, whisk soy sauce, honey, rice vinegar, sriracha, and 2 teaspoons cornstarch.
Whisk in the water or broth until smooth. Taste and adjust sweetness or heat.
Sear the shrimp: Heat a large skillet or wok over medium-high. Add 1 tablespoon oil.
Cook shrimp in a single layer for 1–2 minutes per side until pink and just cooked through. Transfer to a plate.
Sauté aromatics: In the same pan, lower heat to medium. Add garlic and ginger.
Cook 30 seconds until fragrant, stirring so it doesn’t burn.
Add veggies: Toss in your vegetables. Stir-fry 2–3 minutes (spinach will wilt faster; add it at the end). Season lightly with salt.
Gloss with sauce: Stir the sauce again (cornstarch settles) and pour into the pan.
Simmer 1 minute until it thickens and turns glossy.
Toss noodles and shrimp: Add cooked noodles and shrimp back to the pan. Toss well so everything gets coated. Drizzle with toasted sesame oil and scatter most of the green onions.
Finish and serve: Taste and adjust soy, honey, or heat.
Plate with remaining green onions, sesame seeds, and lime wedges if you like a bright finish.
