Follow these simple steps to create delicious burger sliders with garlic aioli:

1. Prepare the Garlic Aioli: In a small bowl, combine mayonnaise, minced garlic, lemon juice, salt, and black pepper. Mix well and set aside in the refrigerator to let the flavors meld.

2. Make the Burger Mixture: In a large bowl, combine the ground beef, garlic powder, onion powder, salt, and black pepper. Mix gently until just combined, being careful not to overwork the meat.

3. Form Sliders: Divide the beef mixture into 12 equal portions and shape them into small patties, about 2-3 inches wide. Make a slight indentation in the center of each patty to ensure even cooking.

4. Preheat the Grill or Skillet: If using a grill, preheat it to medium-high heat. If using a skillet, heat it over medium heat and add a little oil to prevent sticking.

5. Cook the Sliders: Place the patties on the grill or skillet and cook for about 3-4 minutes on each side for medium doneness. If using cheese, add a slice on top of each slider during the last minute of cooking to melt.

6. Toast the Slider Buns: While the sliders are cooking, slice the buns and toast them on the grill or in a separate pan until golden brown.

7. Assemble the Sliders: Spread a generous amount of garlic aioli on the bottom half of each toasted bun. Place a cooked slider patty on top, followed by lettuce, tomato slices, and pickles if desired. Finish with the top half of the bun.

8. Serve Immediately: Arrange the sliders on a serving platter and watch them disappear!
