In a large bowl, mix the Simple Truth™ ⁹⁰⁄₁₀ Ground Beef with the Worcestershire sauce, salt, pepper, garlic powder, and shallot until just combined.
2. Step
Divide the beef mixture into 18 balls (about 1–1½ tablespoons each) and flatten into ½”-thick patties.
3. Step
Using a 2–2½” ring cookie cutter, cut each side of the slider buns into small rounds.
4. Step
Heat a large frying pan over medium-high heat. Toast the buns, cut sides down, for 20 seconds, or until golden brown. Set aside.
5. Step
Heat the olive oil in the same skillet. Working in batches, add the beef patties and cook for 90 seconds. Flip and reduce the heat to medium. Place a quarter slice of cheddar on top of each patty and cook for 90 seconds more, or until the cheese is melted and the patties are cooked through. Remove from the pan and repeat with the remaining patties and cheese.
6. Step
Make the avocado dip: In a blender, combine the avocado flesh, Greek yogurt, mayonnaise, garlic, lime juice, and salt. Blend on high speed for 1–2 minutes, until smooth. Season with more salt to taste.
7. Step
Assemble the skewers: Thread a toasted bottom bun onto a skewer, followed by a beef patty, a piece of lettuce, a tomato half, a piece of red onion, and a pickle slice. Repeat stacking the ingredients from the beef patty to the pickle 2 more times, then finish with a top bun. Repeat to make 5 more skewers.
8. Step
Serve the skewers immediately with the avocado dip and Simple Truth™ No Sugar Added Ketchup for dipping.
