• 3 cups cooked beef, cut into bite-size pieces
• 1 cup chopped onion

• 2 1/4 cups milk

Heat oven to 350°. Grease a 13x9x2-inch baking dish.

Layer beef, onion, celery, tomatoes and shredded cheese in the baking dish. Beat remaining ingredients until smooth, about 20 seconds in blender or 1 minute with electric hand-held mixer on high.

Pour egg mixture over layers. Bake for about 45 minutes, or until knife inserted in center comes out clean. Let stand for 5 minutes before serving.
