  • 2 Tbsp avocado oil
  • 1/2 small yellow onion, chopped
  • 16 oz. mushrooms, sliced
  • 2 medium zucchini, spiralized into noodles
  • 1 tsp garlic powder
  • 1/2 cup cashew butter

  • 1/4 cup grated vegan cheese

  • Heat the avocado oil in a medium skillet over medium-high heat.
  • Add the chopped onion and mushrooms, cooking for 7-10 minutes until the mushrooms are golden and tender.
  • Spiralize your zucchini into noodles, then add them to the skillet. Sauté for another 5-7 minutes, just until the zoodles are al dente.
