Place the broccoli in the microwave in a covered dish with a little bit of water. Cook on high until the broccoli is tender, but still crisp. This takes approximately 5-6 minutes. Drain.
In a small dish, melt the butter and add the remaining ingredients. Spread the broccoli on a foil lined broiler safe tray and then sprinkle with the Panko topping. Broil for 4-5 minutes or until lightly browned.
