Spicy Bok Choy in Garlic Sauce

Step 1
Trim ends from bok choy and discard. Chop bok choy, keeping white stems and green leaves separate. Rinse, then spin or pat dry.

Step 2
Stir water, garlic, oyster sauce, soy sauce, brown sugar, ginger, and pepper flakes together in a bowl.

Step 3
Heat both oils together in a wok over medium-high heat. Add bok choy stems and stir-fry until they start to turn pale green, 2 to 3 minutes. Add bok choy leaves and stir-fry until wilted, 1 to 2 minutes. Remove from the heat and transfer to a serving dish.

Step 4
Pour sauce into the wok and return to the stovetop over medium-high heat. Cook, stirring constantly, until sauce has thickened slightly, about 3 minutes.

Step 5
Pour sauce over bok choy and toss lightly to coat.
