Step 1

Position rack in upper third of oven; preheat broiler to high.

Step 2

Heat 2 tablespoons oil, garlic and crushed red pepper in a large nonstick skillet over medium-high heat. As soon as the garlic starts to sizzle, add turkey, fennel seeds, paprika and 1/8 teaspoon salt. Cook, breaking up the turkey with a wooden spoon, until it is almost cooked, 2 to 3 minutes. Add kale, vinegar and the remaining 1/8 teaspoon salt; cook, stirring, until the kale is wilted and the turkey is no longer pink, 2 to 3 minutes more. Remove from heat.

Step 3

Place naan (or pitas) on a large baking sheet and brush with the remaining 1 tablespoon oil. Top with equal portions of the turkey mixture and mozzarella.

Step 4

Broil until the cheese is melted and the edges are starting to brown, 2 to 4 minutes. Cut in half.
