Brown the Beef: In a large skillet, heat over medium-high heat and add the ground beef. Cook for approximately 6–8 minutes, breaking it apart with a spatula as it browns. Aim for the beef to be fully cooked, with no pink remaining.

Sauté the Onions: Once the beef is cooked through, add the diced onion to the skillet. Sauté for about 3–4 minutes, stirring frequently until the onions become soft and translucent.

Mix in Flavorful Ingredients: Stir in the chopped dill pickles, Worcestershire sauce, yellow mustard, salt, and pepper. Allow these ingredients to cook together for about 2 minutes, mixing well.

Create the Creamy Base: Lower the heat to medium-low and add the shredded cheddar cheese, softened cream cheese, and plain Greek yogurt to the skillet. Stir continuously for around 3–5 minutes until the mixture is smooth and creamy.

Assemble and Serve: Remove the skillet from heat and top with a handful of shredded lettuce and a sprinkle of sesame seeds. Serve warm in bowls or use low-carb wraps.
