Heat your oven to 425.

Skin and cut up your sweet potatoes into bite sized chunks. Wash and cut up your mushrooms as well.

In a bowl melt the butter with the miso in a microwave for 15-20 seconds.

Put mushrooms and sweet potatoes onto a baking tray and toss on the tray with olive oil, the melted butter and miso, garlic and salt and pepper to taste.

Place tray in the oven for 30 minutes tossing once at 15 minutes.

After 30 minutes take it out of the oven and top with chopped parsley.

Enjoy!
