In a small bowl, make the "special sauce" Stir together ½ cup mayonnaise, 2 Tablespoons French dressing, 1 Tablespoon dill pickle relish, 1 Tablespoon dried minced onion, 1 ½ teaspoons granulated sugar, 1 teaspoon white vinegar, 1 clove garlic, minced and pinch of kosher salt. Place in the refrigerator until ready to use.
In a large bowl add 1 pound lean ground beef, 2 teaspoons Worcestershire sauce, 1 teaspoon garlic powder, and 1 teaspoon onion powder. Mix until combined, I like to do this by hand.
Portion the meat into 9 portions. Roll them into balls and place them on a sheet tray covered with plastic wrap for easy clean-up. Place them about 2 inches apart. Add another layer of plastic wrap on top.
Press them down flat, I like to use the bottom of a drinking glass to do this. Remove the top layer of plastic wrap.
Heat a large skillet over medium heat. Once hot, add the burger patties to the skillet, do not crowd the pan, no need to add any oil to the pan, there is enough fat in the meat. Brown on both sides for about 3 minutes, or an internal temperature reaches 140°F. You may need to do this in batches.
Place the bottom half of the 9 Hawaiian slider rolls into a 9x9 baking dish. Place the burger patties on top of each slider bun.
Top with 4 slices American cheese. Top each slider with 2 of the 18 pickle chips. Drizzle with ketchup and mustard.
Add half of the special sauce on top.
Cover with the top half of the buns. Cover with foil and bake for 15 minutes.
Take off the foil and brush the tops of the buns with 2 Tablespoons unsalted butter, melted, use it all! Sprinkle 1 teaspoon sesame seeds all over the top. Bake for an additional 5 minutes uncovered to toast the buns.
Serve with more special sauce on the side for dipping.
