- Combine soy sauce, vinegar and chile-garlic sauce in a small bowl.
- Heat oil in a wok or large skillet over medium-high heat. Add ginger; cook until fragrant, about 30 seconds. Add snow peas, radishes and scallions; cook, stirring frequently, until the peas are tender-crisp, 2 to 4 minutes. Add the sauce and stir to coat well. Remove from the heat; stir in cashews.
