Preheat oven to 400 degrees. Wash potatoes thoroughly; pat dry. Cut potatoes into French fry size pieces and place in a big bowl with a lid. Pour olive oil over potatoes and then add the pesto sauce mix. Place lid on bowl and shake until all potatoes are evenly coated with pesto. Spread potatoes on a foil-lined cookie sheet sprayed with non-stick cooking spray. Bake for 30 minutes. Meanwhile, prepare dipping sauce. Place sun-dried tomatoes, tomato paste, water, garlic powder, ricotta cheese, and parmesan cheese in a food processor or blender. Blend until all ingredients are combined and smooth. When potatoes are done, turn broiler on high and broil fries 5-10 minutes until golden brown and slightly crispy. Serve with dipping sauce.
