1 Combine mayonnaise, ketchup, relish, sugar, white vinegar, pickles, and pickle juice in a food processor. Process until almost smooth. Season to taste with plenty of black pepper and a little salt (depending on how salty your pickles were, you may not need any extra salt). Set spread aside.
2 Heat an electric griddle to 400°F (200°C). Squirt 12 dots of mustard of about 3/4-teaspoons each in an evenly spaced grid over the surface of the griddle, leaving about 3-inches between each dot. Place one ball of meat on top of each dollop. Season generously with salt and pepper, then smash down with a stiff spatula into patties approximately 1/4-inch thick and 3-inches wide. Spread onions evenly over surface of burger patties and press down with spatula. Allow to cook for 1 minute on first side.
3 Flip patties so that onions are underneath (patties will not necessarily be colored—this is ok; the flavor in sliders comes from steam, not from browning). Top each patty with a half slice of American cheese. Place top buns cut-side-down on top of patties and top with bottom buns, also cut-side-down. Drape a towel over the whole griddle to trap steam.
4 Cook, pressing gently down on towel occasionally until buns are heated completely through and burger patties are cooked, about 2 minutes. Remove towel and transfer bottom buns to a serving platter. Divide spread evenly between bottom buns. Top each bottom bun with a burger patty and top bun, making sure to get all of the onions off of the griddle. Serve immediately.
