Preheat your oven to 400°F (200°C) and line a small baking sheet with parchment paper.
Dice the potato into 1/2-inch cubes and place them on the baking sheet.
Toss the potatoes with 1 teaspoon of olive oil, half of the dried rosemary, and a pinch of the salt and pepper.
Roast the potatoes for 15 minutes, then add the cherry tomatoes to the same tray and roast for an additional 10 minutes until the tomatoes burst and potatoes are golden.
While the vegetables roast, season the pork chop on both sides with garlic powder, the remaining rosemary, salt, and pepper.
Heat the remaining 1 teaspoon of olive oil in a heavy-bottomed skillet over medium-high heat.
Sear the pork chop for 4 to 5 minutes per side, or until the internal temperature reaches 145°F.
Remove the pork from the pan and let it rest for 3 to 5 minutes to lock in the juices before serving with the roasted potatoes and tomatoes.
