Grease a deep pie plate.
Spread the cooked broccoli*, onions, and cheese in the bottom of the pie plate.
Beat together the eggs, bisquick and milk.
Add the seasonings.
Pour into pie plate.
Bake at 350 degrees for 35 minutes or until "puffy" and center is set.
NOTE: I have added 1/2 cup crumbled bacon, chopped ham and have switched out the cheddar with Swiss cheese and used spinach instead of the broccoli. Nice changes with great, delicious results!
