For the fries: Bake the waffle fries according to the instructions on the package.
For the slider patties: Add the ground beef to a bowl and mix together with the garlic powder, lemon pepper, seasoned salt, salt and pepper. Mix together well with your hands and form eight 2-ounce patties. Set the patties aside on a plate.
Heat the vegetable oil in a large nonstick skillet over medium-high heat. Add the patties to the skillet and cook for 3 minutes. Flip the patties and allow them to cook for 30 to 45 seconds, then top each patty with a quarter slice of cheese. Cover the skillet and cook for another 3 minutes. (The lid will help the cheese melt over the patties.)
Remove the patties to a plate.
For the sliders: Top a waffle fry with a piece of lettuce, then top with 1 teaspoon ketchup and 1 teaspoon mayo. Add red onion and a patty on top. Top the patty with a Roma tomato slice and then a pickle slice. Place a waffle fry on top and secure with a toothpick. Repeat 7 more times and enjoy!
