Preheat oven to 425° F. Spread frozen fries in a single layer on a dark, non-stick baking sheet or shallow baking pan. Bake according to the instructions on the packaging (no flipping required!). Waffle Fries: 8-10 mins. Straight and Crinkle Fries: 10-13 mins
While fries are baking, cook ground beef in a skillet over medium-high heat, adding steak seasoning or just salt and pepper as desired. Cook until all meat is brown then drain and set aside.
When fries are done, arrange them on a platter or serving skillet leaving open space in the center. Add cooked ground beef to the center.
Drizzle fries and beef with nacho cheese sauce then layer on shredded lettuce, halved grape tomatoes, red onion slices, and pickles. Add ketchup and mustard if desired plus bacon and avocado slices if you'd like to include those optional toppings.
Serve hot! Offer individual plates and a spatula for transferring to the plates or serve as finger food.
