Whisk egg slightly in a large bowl; blend in mayonnaise and soup. Stir in broccoli, onion and cheese. Pour into a lightly greased 1-1/2 quart casserole dish. Toss together crumbs and butter; top casserole with crumb mixture and sprinkle with paprika. Bake, uncovered, at 350 degrees until bubbly, about 35 minutes.
Tip: Flash-frozen vegetables come in so many different varieties. Stock the freezer with your family's favorites and you'll always be ready to whip up a delicious side dish or hearty soup at a moment's notice.
