The video shows this recipe prepared with cooking the onions and peppers separately from the mushrooms. I am allergic to mushrooms and so it is a no go for me on mushrooms. But Mushrooms have so much medicinal benefits eating them may provide protection from cancer, diabetes and help your heart. I wouldn't want my family to miss out on those so I dirty another pan- that my kids then have to wash. Overall this meal is a really great way to eat a lot of servings of vegetables and it tastes great!
