To Make the Parmesan Crips:
Microwave: Spray a microwave safe plate with cooking spray. Form parmesan into 4 even mounds on the plate (2 tbs parmesan each), and microwave for 30-60 seconds, or until the parmesan melts and starts to harden into a crisp.
Oven: Preheat oven to 400 degrees. Line a baking pan with foil or parchment paper and spray with cooking spray. Form parmesan into 4 even mounds on the baking pan (2 tbs parmesan each), and bake for 3-5, or until the parmesan melts and starts to bake into a crisp.
Meanwhile, combine everything for the dressing in a small bowl, and whisk together until combined. Refrigerate dressing until ready to serve the salad. To assemble the salad, combine the chopped lettuce, tomato, bacon, and parmesan crisps. Toss to coat in the dressing just before serving.
