Chicken Tacos in Cabbage "Tortillas"

Bring a large pot of water to a boil. Slice the stem end off cabbage and discard the outermost leaves. Peel 8 leaves from the head. Blanch in the boiling water for 30 seconds. Transfer to a paper-towel-lined baking sheet to dry. Thinly slice enough of the remaining cabbage to get 3 cups.

Season chicken with 1/4 teaspoon salt. Heat 1 tablespoon oil in a large skillet over medium-high heat. Add the chicken and cook, stirring, until browned and just cooked through, 5 to 7 minutes. Transfer to a plate.

Add 1 tablespoon oil and onion to the skillet. Reduce heat to medium and cook, stirring, until starting to brown, 3 to 4 minutes. Add garlic, jalapeño and cumin and cook for 1 minute more. Stir in the chicken and any accumulated juices. Cover to keep warm.

Combine the reserved sliced cabbage, carrot, cilantro and scallion in a medium bowl. Add the remaining 1 tablespoon oil, vinegar and the remaining 1/4 teaspoon salt and stir to combine.

Divide the chicken mixture among the cabbage leaves and top with the slaw.
