1⁄4 cup each 2% plain Greek yogurt and light mayonnaise
1 clove garlic, optional
1 large tomato
1⁄2 small red onion
4 lettuce leaves
4 burger buns
Preparation
In a large fry pan, heat oil over medium-high heat.
Meanwhile, in a bowl, combine ground beef and 2 tbsp dressing mix. Form into four pucks (do not form patties).
Add pucks to pan, leaving enough room to smash them down. Work in batches, if necessary. Using a spatula, press down on each puck until they’re smashed and thinned out. Cook 3–4 min per side, or until the edges start to brown.
To make sauce, combine yogurt, mayonnaise, and remaining 1⁄2 tbsp dressing mix. Finely chop garlic clove and whisk in, if using. Set aside.
Cut tomato into thick slices; slice onion into rings.
Spread sauce on top and bottom buns. Place patty on bottom bun; top with tomato, onion, and lettuce. Cover.
