1In a medium saucepan, heat oil over medium heat then add sage leaves and fry for 30 seconds.
2Add baby bella mushrooms and onion. Sautee until onion and mushrooms are browned. About 5 minutes on medium heat.
3Add garlic, rosemary, thyme and cook for another 30 seconds. Then add the all-purpose flour and mix until the oil absorbs the flour. Then add nutritional yeast and red miso.
4Add vegetable broth 1/2 cup at a time while mixing. Once gravy has thickened add another 1/2 cup. Add vegetable broth until desired consistency. Will thicken a bit when you blend it in the next step, so it's ok if its a little runny.
5Add salt and pepper, then let cool for 5 minutes. Place in a blender and blend until smooth. It will be hot still so make sure the some air is allowed to escape from the top. Blend on low.
