Preheat oven to 475°F.
In a large bowl, mix 3 tablespoons olive oil, the lemon juice, thyme, paprika and garlic; season with salt and pepper. Add the pork chops and turn to coat.
On a large, rimmed baking sheet, toss the green beans, potatoes and red peppers with the remaining 3 tablespoons olive oil; season. Spread in an even layer. Nestle the pork chops among the vegetables.
Roast, turning the pork chops once, until the vegetables are tender and the chops are just cooked through, about 25 minutes.
