Place a large skillet over medium heat and coat lightly with cooking spray. Add in the bacon and cook for 3-5 minutes and then flip over, cooking for another 2-3 minutes. Once done, remove and place on a paper-towel lined plate.Remove all of the oil from the bacon except for 2 tbsp. Add in the garlic and red pepper flakes and cook for 30 seconds. Then, add in the zucchini noodles and toss to cook, for about 2-3 minutes.Season the zucchini with about 5 cracks of the pepper and add in the cheeses. Toss to combine thoroughly and then plate into two bowls. Top each bowl with a few more cranks of black pepper and crumble over a piece and a half of bacon in each bowl. Garnish with additional parmigiano reggiano cheese.
