Add minced garlic and cook for 30 seconds, then deglaze with vegetable broth. Reduce heat and cook for 1-2 minutes. Remove mushrooms and set aside.
In the same skillet, cook minced onion for 1 minute until translucent. Add spinach and cook for 2 minutes until wilted. Season with salt and pepper.
Combine cooked quinoa, mushrooms, spinach, parmesan cheese, Italian seasoning, and red chili pepper flakes in the skillet. Serve hot with additional parmesan and chili flakes if desired.
Notes
Adjust the amount of red chili pepper flakes based on desired spiciness. Serve hot and enjoy!
