Preheat the oven to 400 F degrees. Soak brussels sprouts in water and some white vinegar to clean for about 10 minutes to clean & rinse. Cut stems off and halve the brussels sprouts vertically and place on a parchment lined baking sheet. Season brussels sprouts liberally with salt & pepper and coat with avocado oil. Add pancetta to the baking sheet and mix everything together with a spoon to coat the oil and seasonings to the brussels sprouts. Turn all brussels sprouts down so that the open centers are directly on the backing sheet
Bake for 25 mins or until fork tender and pancetta is browned and crispy, remove from oven
While the brussels sprouts and pancetta are roasting in the oven, make the vinaigrette by mixing all ingredients together in a mason jar, shake well
Add cooked brussels sprouts and pancetta to a bowl and top with dried cranberries, parmesan cheese, and vinaigrette, toss together and serve
