Place a large skillet over medium heat and add in olive oil.
Snap the bottoms off the asparagus and then shave with a vegetable peeler, starting from the bottom of the asparagus tips all the way down to the end of the stalk.
Add the sweet potato noodles, garlic, red pepper flakes, and pepper to the skillet. Toss to combine and then add in the broth and parsley. Let cook, stirring occassionally, for 6-8 minutes or until sweet potato noodles are cooked through and soften. After 5 minutes into the noodles cooking, add in the shaved asparagus and asparagus tips. Toss to cobine and let the noodles finish cooking.
