Ingredients

Preparation

2 kaiser rolls, cut into cubes
1/4 cup extra-virgin olive oil, plus more for brushing
Salt and pepper
1/3 cup mayonnaise
3 tbsp lemon juice
1/4 cup grated parmesan cheese
1 1/2 tsp Dijon mustard
1 1/2 lbs ground beef
One 12-oz package romaine hearts, torn into small pieces

2.  Meanwhile, in a large bowl, whisk together the mayonnaise, lemon juice, 3 tbsp parmesan, mustard and remaining 2 tbsp olive oil; season with salt and pepper.

3.  Crumble the beef into a medium bowl, season with salt and pepper and toss.  Divide into 12 equal portions and roll into balls.  Thread 3 meatballs onto each of 4 wooden skewers, leaving a 1/2 inch space between each; pat each meatball into a 2-inch patty.

4.  Preheat a grill pan over medium heat.  Brush the patties with olive oil and grill, turning once, about 6 minutes total for medium.

5.  Meanwhile, add the lettuce and croutons to the dressing and toss.  Sprinkle with the remaining 1 tbsp parmesan and season with salt and pepper.  Top with the skewers.
