Croutons: Preheat oven to 350° and place bread cubes on a baking sheet. Spray cubes generously with cooking spray and sprinkle with salt and pepper to taste.

Toast cubes until light golden brown (6–8 minutes) like your favorite croutons (pre-made croutons also work)

Dressing: Combine lemon juice, oil, garlic, mustard, salt, and pepper in an air-tight container. Shake vigorously (or mix well) until the dressing is combined.

Chop the romaine lettuce and add to a large bowl. Toss to coat greens with desired amount of dressing and croutons.

Enjoy as is or sprinkle parmesan or your choice of protein!
