Preheat oven to 400⁰F degrees. Place Bonmat on Perforated Baking Sheet and set aside.
Using your Mandoline, slice the potatoes in ¼” slices.
Create 1 layer of sweet potatoes on Bonmat. Make sure they overlap each other. Brush with olive oil and sprinkle ¼ tsp of your Roasted Garlic and Chive herb blend. Top with salt and pepper. Add another layer of the potatoes on top of first layer and repeat with the oil, herbs and salt and pepper. Continue for 4—5 layers.
Cook for 20 minutes or until potatoes are tender. The last 2 minutes add parmesan cheese.
