I love this recipe because it takes all the wonderful cheesy and peppery flavors of classic cacio e pepe pasta and lightens it up with leafy greens. It's incredibly flavorful and a great dish to perk up your palate at the start of a meal.
For the dressing:
In a small blender, add all ingredients and blend for 20 seconds or until nicely emulsified.
For the salad:
Brush a healthy amount of the dressing on the cut side of the lettuces.
Place the lettuces on a plate, drizzle with small amount of balsamic vinegar, shave nice amount of Parmigiano and add lots of coarse ground pepper on top.
