The mushrooms and walnuts play off each other to create some semblance of ground beef, and the flavors do not disappoint. Whether you are plant-based or a meat-eater, give this sauce.
Heat the olive oil over medium heat.
Add the onions, broccoli and mushrooms. Saute for 5-10 minutes or until soft.
Serve warm over spaghetti squash or zoodles.
