Heat a medium skillet over medium heat and add oil.
Add garlic to the skillet and sauté until fragrant and lightly brown, about 3 minutes. Be careful not to burn.
Add in the sweet potato noodles and toss to coat with oil and garlic.
Add a pinch of salt and pepper. Cook for 2 minutes, tossing frequently.
Add water to the pan and toss to make sure noodles are evenly coated.
Cover and cook for 5 more minutes or just until soft, checking frequently.
Add the spinach and toss to distribute.
Turn off the heat, cover, and let sit for 2 minutes, or until the spinach is wilted.
Serve with a sprinkle of Parmesan cheese.
