Not a recipe exactly, but...
Mushroom broth from a pound of baby Bella. Clove of garlic, confit in oil until brown. Can of Merazano tomatoes. Combine, slow simmer with fresh oregano. Blend, salt to taste.
I happened to buy some mushroom broth powder at an Italian grocery store recently, so maybe I can try using it for this; do you know how that's likely to compare to a broth made from fresh mushrooms?
Better than any can sauce I've had
