Brown ground beef in a skillet over medium-high heat. Add onions and cook until softened.
Stir in pickles, Worcestershire, mustard, and season with salt and pepper.
Lower heat, then mix in cheddar, cream cheese, and Greek yogurt until everything is creamy and well combined.
Top with shredded lettuce or place on a plate of lettuce and add a sprinkle of sesame seeds for the full burger bowl effect.
Serve warm and dig in with a fork—or low-carb wrap if you’re feeling bold.
