Cut the zucchini into thin slices, steam for 2 minutes until barely tender, let cool.  Beat the eggs, than add milk, grated cheese, seasonings, leavening and flour.  Stir cooked zucchini into the egg mixture, pour into a greased 1-1/2 quart pan.  Top with bread crumbs, dot with butter.  Bake at 350 degrees for 35 - 50 minutes.
