Breakfast casseroles that are prepared the night before and then can be popped into the over are great. My sister-in-law used to always put one together in a disposable pan, cover with aluminum foil, and tape the cooking directions on top along with a copy of the recipe and deliver them to people who were ill or who had a death in the family. She brought them over the night before so they were ready to go for breakfast the next day. Reactions were always the same - everyone was so appreciative to have something warm and hearty to serve for breakfast and that was also good warmed up throughout the day and even the next day.
I have adopted this practice and get good responses also.
