Preheat oven to 400 ° F. Combine the first three ingredients in a large pot and bring to a boil. Reduce heat and simmer until tender, about 7 minutes. Drain and let stand for 5 minutes. Coat two 8″ casserole dishes with cooking spray, and split the vegetable mixture between them, layering vegetables evenly.

Melt butter in a skillet over medium-high heat. Add panko, toast until brown. Sprinkle panko over cheese mixture. Bake for 15 minutes or until bubbly. Let stand for a few minutes before serving.
