Cabbage Slaw

Heat a dry medium cast-iron skillet over medium-high. Cook scallions, turning once or twice, until lightly charred in spots, about 3 minutes. Transfer to a blender and add chile, garlic, lime zest and juice, and oil. Blend until smooth; season dressing with salt.

Toss cabbage, radishes, and half of dressing in a large bowl. Taste and season with salt and add more dressing if needed. Top with mint and onion just before serving.
