Ingredients
- 1/2 cup mayo
- 1 tbsp. finely chopped red onion
- 1 tbsp. ketchup
- 1 tbsp. sherry vinegar
- 1 tsp capers, drained and chopped
- 1 tsp chopped fresh parsley
- 1/2 tsp chopped fresh thyme
- 1/8 tsp sugar
- 1 lb. ground beef
- 1 1/2 tsp kosher salt
- 1 tsp black pepper
- 4 tbsp. olive oil
- 3 cheddar cheese slices, cut into quarters
- 12 mini slider brioche buns, split
- 1 small head iceberg lettuce, shredded

Directions
-
Preheat a grill to medium high. Stir together mayo, red onion, ketchup, vinegar, capers, parsley, thyme, and sugar in a small bowl until combined.
-
In a large bowl, add beef, 3/4 tsp salt, and 1/2 tsp pepper. Using your hands, mix together until just combined. Make 12 meatballs by rolling beef mixture in your palms; transfer to a baking sheet. Flatten tops slightly. Drizzle with oil and season both sides with remaining 3/4 tsp salt and 1/2 tsp pepper.
-
Arrange patties on oiled grates; grill, uncovered, 3 minutes. Flip, then top each with 1 cheese piece. Grill, uncovered, until cheese is melted and beef is cooked through, about 2 minutes. Meanwhile, put buns, cut sides down, on grate; grill until toasted, about 1 minute.
-
Top bun bottoms with a small spoonful of sauce. Add a patty, shredded lettuce, tomato slices, cornichon slices and bun tops.
