Heat the butter in a wok or cast-iron skillet over medium-high heat.
Once hot, add the soy sauce and snow peas and toss to coat evenly. Season them with the red pepper flakes, garlic powder, and freshly cracked black pepper to taste.
Cook, stirring often, for 3-4 minutes.
Pour into a serving bowl and sprinkle with toasted sesame seeds to taste.
Serve immediately, along with spicy chili crisp, if desired. Enjoy.
