Preheat the oven to 375F. Combine the cheeses. Divide and place in four ovenproof 1/2-cup ramekins or one 9-inch square ovenproof baking dish. (Do not be concerned if theyre almost overflowing; the heat will melt the cheese down.) Place on a baking tray or cookie sheet for easy handling and bake for 5 minutes, until the cheese begins to soften. Meanwhile, melt the butter in a small skillet over medium-high heat. Saute the zucchini and mushrooms with a sprinkling of black pepper until lightly browned, about 5 minutes. Sprinkle the zucchini and mushrooms over the cheese and place back in the oven about 7 minutes longer, until the cheese is melted and bubbly. Use tongs or pot holders to transfer the dishes to individual serving plates and serve immediately with soft, warm tortillas.
