In a small bowl, whisk together the rice wine, tamari, salt, and ketchup to create the sauce. Prep your vegetables: Cut broccoli florets off the stalk, then peel the stalk and slice it into 1-inch pieces. 2.
Place the broccoli florets and stalks in a wok or large skillet with ½ cup of water.
Cover and steam over high heat for about 1 minute, just until the broccoli turns bright green and crisp-tender. Immediately transfer the broccoli to a plate and discard any remaining water from the pan. 3. Wipe the pan dry and return it to high heat.
Add the peanut oil.
Once hot, add the ginger, garlic, and red pepper flakes, stir-frying constantly for 1 minute until fragrant. 4.
Add the sliced mushrooms and continue to stir-fry for 3 minutes until they release their liquid and begin to brown.
Add the tempeh cubes and cook for another 2 minutes, followed by the blanched broccoli for 2 more minutes. 5. Give the sauce a final stir and pour it over the contents of the wok.
Toss everything together to coat evenly in the glossy sauce.
Serve immediately over a bed of hot brown rice.
