Ingredients

1 pound brussels sprouts, shredded 

1 pound lacinato kale, shredded 

1/4 cup olive oil 

2 shallots, halved lengthwise and thinly sliced crosswise (1/2 cup) 

1 1/2 teaspoons coarse salt 

1/8 teaspoon red-pepper flakes 

2 tablespoons champagne vinegar 

Preparation

Trim ends of brussels sprouts and shred in the bowl of a food processor.

Trim kale, removing thick center stems, and shred.

Heat oil in a large straight-sided saute pan over medium-high heat. When oil shimmers, add shallots and cook until shallots begin to soften and sweat, 1 minute.

Add brussels sprouts, kale, salt, and red-pepper flakes to pan and cook, stirring occasionally, until vegetables are wilted and tender, about 5 minutes. Stir in vinegar, remove from heat, and serve.
