Whisk together 1 tablespoon lemon juice with tomato paste, seasonings (paprika - black pepper), and olive oil. Toss the seasoning mixture with the potatoes until the potatoes are evenly coated. Spread the wedges in an even layer on a baking sheet with rosemary sprigs. Bake the potato wedges for 20 minutes. Flip the potato wedges over and bake for another 15 minutes or until cooked. Serve immediately.
