Ingredients

• 7 oz sweet potato glass noodles
• 1 cup shiitake mushrooms, sliced
• 2 cups baby spinach
• 1 medium carrot, julienned

• 3 tbsp soy sauce
• 1 tbsp sugar
• 2 cloves garlic cloves, minced
• 2 tbsp sesame oil
• 1 tbsp vegetable oil
• 1 tbsp toasted sesame seeds
• 1/4 tsp black pepper

Instructions

1. Step 1: Bring a large pot of water to a boil. Add 7 oz sweet potato glass noodles and cook for 6-7 minutes until soft but chewy. Drain and rinse under cold water, then cut noodles with scissors into 6-inch lengths.

3. Step 3: Add 1/2 sliced onion, 1 julienned carrot, and 2 minced garlic cloves to the skillet, cooking for 3 minutes until vegetables soften and become fragrant.
4. Step 4: Add 2 cups baby spinach and cook until just wilted, about 1 minute. Then add the cooked noodles to the skillet.
5. Step 5: Stir together 3 tbsp soy sauce, 1 tbsp sugar, 2 tbsp sesame oil, and 1/4 tsp black pepper in a small bowl, then pour over the noodle mixture. Toss everything together over medium heat for 2 minutes until noodles are evenly coated and heated through.
6. Step 6: Remove from heat and sprinkle 1 tbsp toasted sesame seeds on top before serving.
