Place all of the ingredients for the Special Sauce into small food chopper or processor. Cream together until smooth. Set aside
Cook the french fries according to package instructions. I like to line a baking sheet with parchment paper (this will make cleanup very easy at the conclusion of this recipe).
While the fries are cooking, cook the ground beef in a large skillet. Be sure to use a spatula to break the beef down into small crumbles as it cooks. Once the meat has cooked through, roughly 6-8 minutes (or until no pink color remains in the meat), drain the meat thoroughly to remove any grease. Return the cooked beef to the skillet and stir in ½ cup Hellman’s Spicy Dipping sauce, ¼ - ½ teaspoon sea salt, and ¼ teaspoon black pepper. Stir together and cook over medium heat for 2-3 minutes. Set aside
Once the fries are cooked to your liking, remove the baking sheet from the oven. Gather the French fries close together in a single layer. Scatter the shredded cheddar cheese over the fries. Top with the cooked ground beef being sure to scatter the beef evenly among the fries, top with the remaining shredded Monterey Jack cheese, and return to the oven (425 degrees) for 5 minutes (or until the cheese has melted).
Remove the fries from the oven and top with chopped lettuce, scallions, and tomatoes
Place the special sauce into a resealable plastic bag. Cut a small corner off of the bag and drizzle the sauce over the top of the loaded nachos.
