These mushrooms get a kick of spicy flavor from homemade chili oil! They can be served over grilled steaks or roasted poultry to add earthy heat to a special dinner. Get even more creative and use them to top your mushroom toast! They pair well with a base layer of hummus or cream cheese. Plan ahead for this one because your chili oil will need to rest at least a couple hours to infuse pleasant heat into the oil.
