Step 1

Preheat oven to 400 degrees F. Coat a 9-by-13-inch baking dish with cooking spray.

Step 2

Whisk water, tomato paste, vinegar, soy sauce, 2 tablespoons hoisin, 1 tablespoon ginger, 2 cloves garlic and crushed red pepper in a small saucepan. Whisk in cornstarch; bring to a simmer over medium-high heat. Cook, stirring, until thickened, about 2 minutes. Remove from heat and set aside.

Step 3

Meanwhile, bring a large pot of water to a boil. Add 4 cabbage leaves and cook, gently stirring, until softened, 1 to 2 minutes. Transfer to a rimmed baking sheet. Repeat with the remaining cabbage leaves. Place broccoli in a colander and pour the hot water over it. Refresh with cold water. Transfer to a large bowl. Add pork, rice, scallions, sesame oil, the remaining 2 tablespoons hoisin, 1 tablespoon ginger and 2 cloves garlic, and 3 tablespoons of the reserved sauce. Stir to combine well.

Step 4

Place 1/3 cup filling over the bottom third of 1 softened cabbage leaf. Fold the bottom and sides over the filling and roll up. Place, seam-side down, in the prepared baking dish. Repeat with the remaining leaves and filling. Pour the remaining sauce over the rolls. Cover with foil and bake until an instant-read thermometer inserted into the center of a roll registers 150 degrees F, about 40 minutes.
