The key to the side dish is to almost burn the brussels sprouts; the charred flavor is irresistible.

ingredients
2    tablespoons   vegetable oil
1/2   cup   Rice Krispies, or other puffed rice cereal
1/4   teaspoon   togarashi or cayenne pepper
    Kosher salt
1/4   cup   Asian fish sauce
2    tablespoons   water
2    tablespoons   sugar
1    tablespoon   rice vinegar
1    tablespoon   fresh lime juice
1      garlic clove, minced
1      small red chile, minced
1/4   cup   chopped cilantro
2    tablespoons   chopped mint
4    cups   roasted or boiled brussels sprouts, halved lengthwise (about 2 pounds)
directions
In a large skillet, heat 1 tablespoon of the oil until shimmering. Add the Rice Krispies and togarashi and cook over high heat, stirring, until browned, about 30 seconds. Season with salt. Transfer to a plate and wipe out the skillet.
In a small bowl, combine the fish sauce, water, sugar, rice vinegar, lime juice, garlic and chile and stir until the sugar is dissolved. Add the cilantro and mint.
Add the remaining 1 tablespoon of oil to the skillet and heat until nearly smoking. Add the brussels sprouts; cook over high heat, stirring, until charred in spots and heated through, about 5 minutes. Transfer to a bowl and toss with the vinaigrette. Just before serving, sprinkle the Rice Krispies on top and serve right away.
