Heat oil in a wok or large skillet over medium-high heat.
Add garlic and Thai chili ; stir-fry until fragrant, about 30 seconds.
Bring in onion. Stir occasionally until the onion cooks through, about a min.
Toss in the shrimp and stir-fry until they just start to turn pink, 2 mins.
Add ginger, peppers and chili, if using. Stir occasionally, for a minute.
Drizzle in Thaimee All-Purpose Sauce and toss to coat. Cook for 1–2 more minutes, until shrimp are cooked through and vegetables are tender-crisp.
Taste and adjust seasoning if needed. Serve hot with steamed rice.
