Preheat the grill to medium-high heat.

In a bowl, mix the ground beef with salt and pepper.

Form the mixture into 4 equal patties.

Brush the grill with olive oil and grill the patties for about 5-7 minutes on each side, or until cooked to your preference.

In a large mixing bowl, combine the chopped romaine lettuce, cherry tomatoes, cucumber, and pickles.

Once the patties are cooked, slice them into strips and add them to the bowl.

Sprinkle the shredded cheddar cheese on top.

In a small bowl, mix together the ketchup, mustard, mayonnaise, and apple cider vinegar to create the dressing.

Drizzle the dressing over the salad and toss gently to combine.
