Combine all sauce ingredients in a small food processor or blender. Process until a smooth paste. Set aside.
Place a large skillet over medium heat and coat with cooking spray. Lay in the coppa or prosciutto slices and cook for 3-5 minutes or until crispy. Transfer to a paper towel-lined plate and set aside.
Using the same skillet, add a little oil and spiralized sweet potato noodles and cook, frequently tossing, for about 5 minutes or until sweet potato noodles are al dente.
Transfer to a plate or bowl.
Using the same skillet, stir in the spinach and cook until just wilted.
Stir in sweet potato noodles and sauce. Stir well until heated through.
Crumble the prosciutto/coppa over the skillet, with your fingers.
Give a toss and then remove from heat and serve.
