Crunchy Fish Sticks and Veggies with Dipping Sauce

Heat the oven to 425 degrees F. Bring a large pot of water to a boil. Add the potatoes and 1 teaspoon salt and cook until just tender, 12 to 15 minutes, adding the green beans during the last 4 minutes of cooking. Drain and run under cold water to cool. Slice the potatoes. Meanwhile, line a baking sheet with nonstick foil. In a shallow bowl, combine the bread crumbs, oil, paprika, half the parsley, 1/2 teaspoon salt, and 1/4 teaspoon pepper. Cut the tilapia diagonally into 1 1/2-inch-thick strips and coat in the bread crumb mixture, pressing gently to help it adhere. Transfer to the prepared baking sheet and cook until golden brown and opaque throughout, 8 to 10 minutes. While the fish is cooking, in a medium bowl, combine the mayonnaise, pickles, mustard, and remaining parsley. Serve the fish and vegetables with the dipping sauce and lemon wedges, if desired.
