Preheat oven to 425°F. Spray a rimmed baking sheet with cooking spray.
Vertically slice cabbage into about 1-inch slices. Place on baking sheet. Lightly brush both sides with 1 tablespoon oil. Bake for 15 to 20 minutes until cabbage is tender.
Place apple juice and vinegar in a small saucepan over high heat. Cook for 3 to 4 minutes until reduced by two-thirds. Remove from heat and add 1-1/2 teaspoons oil, cinnamon, cayenne pepper and salt. Mix well. Drizzle over cabbage the last 5 minutes of cooking.
