Step 1

In a small bowl, combine the mirin, soy sauce, and 1/2 tsp. salt.

Step 2

Heat a 14-inch flat-bottom wok (or a 12-inch heavy-duty skillet) over high heat. Swirl in the oil. Add the carrots and radishes and stir-fry until the edges begin to brown, 5 to 7 minutes. Add the garlic and ginger, and continue to stir-fry until the vegetables are crisp-tender, about 2 minutes more.

Step 3

Add the edamame and soy sauce mixture and stir-fry until just heated through, about 1 minute. Stir in the sesame seeds and serve.
