Creating Filet-O-Fish Sliders involves a few simple steps. Follow these instructions to ensure success:

1. Prepare the Breading Station: Set up three bowls. In the first, place the flour mixed with salt, pepper, garlic powder, and onion powder. In the second bowl, beat the eggs. In the third bowl, add the breadcrumbs.

2. Coat the Fish: Cut the fish fillets into slider-sized pieces. Dredge each piece in the flour mixture, then dip it into the beaten eggs, and finally coat it with breadcrumbs. Ensure each piece is well-coated for maximum crunch.

3. Heat the Oil: In a large skillet, heat about 1/2 inch of vegetable oil over medium heat until it reaches 350°F (175°C).

4. Fry the Fish: Carefully place the breaded fish pieces in the hot oil, making sure not to overcrowd the pan. Fry for 3-4 minutes on each side or until golden brown and crispy. Use a slotted spoon to transfer them to a paper towel-lined plate to drain excess oil.

5. Prepare the Buns: While the fish is frying, lightly toast the slider buns in another skillet or in the oven until golden.

6. Assemble the Sliders: Spread a generous amount of tartar sauce on the bottom half of each slider bun. Place a piece of fried fish on top, followed by a slice of cheese (if using), and a leaf of lettuce. Top with pickles, if desired, and close with the top half of the bun.

7. Serve Warm: Arrange the sliders on a serving platter and serve immediately while they are fresh and warm.
