Adjust racks to middle and top positions and preheat oven to 450 degrees. Wash and dry produce.

Slice potatoes into ¼-inch-thick rounds.

Pat pork* dry with paper towels and season all over with half the Fry Seasoning (you’ll use the rest in the next step), salt, and pepper.

Lightly oil a baking sheet.

In a large bowl, combine potatoes, 2 TBSP oil (¼ cup for 4 servings), remaining Fry Seasoning, and a couple big pinches of salt and pepper; toss until potatoes are completely coated. Arrange potatoes on prepared sheet in clusters (about 6 slightly overlapping slices each).

Roast on middle rack for 10 minutes.

Meanwhile, toss green beans on a second baking sheet with a drizzle of oil, salt, and pepper; push to one side.

Heat a large drizzle of oil in a medium pan over medium-high heat (use a large pan for 4 servings). Add pork and sear, turning occasionally, until browned all over, 4-8 minutes.

Turn off heat. Transfer pork to empty side of sheet with green beans.

Once potatoes have roasted 10 minutes, remove sheet from oven. Sprinkle each cluster with Parmesan. Return to middle rack.

Place sheet with green beans and pork on top rack.

Roast until cheese is lightly browned, potatoes and green beans are tender, and pork is cooked through, 10-12 minutes.

Meanwhile, wipe out pan used for pork and return to medium-high heat. Once hot, pour in ¼ cup water (⅓ cup for 4 servings), jam, mustard, and stock concentrate; whisk to combine. Bring to a simmer and cook until thoroughly combined and thickened, 2-4 minutes.

Turn off heat. Stir in 1 TBSP butter (2 TBSP for 4) until melted. Season with salt and pepper.

Let pork rest 5 minutes after roasting, then slice crosswise.

Divide pork, Parmesan potatoes, and green beans between plates. Spoon mustard apricot sauce over pork and serve.
