Buying pre-sliced fresh mushrooms instead of canned saves time-making this a super-quick fix for low calories and full flavor. Serve these mushrooms on their own as a side or on top of chicken, pork or fish.
Heat the butter in a large skillet over medium-high heat. Add the mushrooms in an even layer and sprinkle with the lemon zest. Cook, undisturbed, until browned, about 2 minutes. Toss with 1/4 teaspoon salt and 3/4 teaspoon pepper and continue to cook until the mushrooms are tender but not mushy, 4 to 5 minutes. Add additional salt and pepper to taste. Transfer to a serving dish and sprinkle with the chives. Serve warm.
