Mushrooms are best in late spring and early summer, but they seem like a wintry accompaniment. Regardless, I love to serve them with steak whenever they are available. This recipe lightens up savory mushrooms a bit making the dish approachable for the spring and summer.

I’ve included a quick vinaigrette recipe to finish the mushrooms and onions. It’s a great item to have on hand and adds flavor to any veggies you’re serving.
