Hi Judy, this is one of my go-to's. A breakfast strata, you can interchage all the ingredients with something else or something more, except for the eggs, they are the glue.
It can be served piping hot or cold from the fridge, good both ways.
I am giving a google result so you can see some of the different options. I make mine in a 8X13 long casserole
It freezes well too.
