Step 1

Position racks in upper and lower thirds of oven; preheat to 425 degrees F. Coat 2 large rimmed baking sheets with cooking spray.

Step 2

Combine apples, leeks, 2 tablespoons oil and 1/4 teaspoon each salt and pepper in a large bowl. Spread onto one prepared baking sheet. (Reserve the bowl.) Roast on the lower rack, stirring once or twice, until the apples are tender and the leeks are wilted, 20 to 25 minutes.

Step 3

Meanwhile, combine curry powder, the remaining 1 tablespoon oil and remaining 1/4 teaspoon each salt and pepper in a small bowl. Spread the mixture on both sides of pork chops and let stand until the apple mixture is almost done.

Step 4

Leaving the apple mixture in the oven, turn the broiler on high. Place the pork chops on the second baking sheet and broil on the upper rack until an instant-read thermometer inserted horizontally into a chop without touching bone registers 145 degrees F, 4 to 6 minutes.

Step 5

Combine vinegar and brown sugar in the large bowl. Add the apple mixture and toss to combine. Serve with the pork chops.
