Tear croissants (or English muffins) into bite-sized pieces and lightly toast using a toaster oven. (You can also use toast, hashbrowns, bagels or croissants instead of English muffins! My favorites are croissants or hashbrowns)
Use butter to grease a large casserole dish.
Whisk eggs together in a large bowl and add salt and pepper.
Add toasted croissant pieces and chopped ham to casserole dish. Pour eggs over top.
Cover with foil and bake at 350˚for 20-35 minutes or until eggs are just set (not watery). (Cook time varies greatly with pan size so keep an eye on things! Flatter pans cook faster)
Top with warm Hollandaise sauce and fresh or dried chives. Cut into squares and serve hot!
