We make 1-2 packets of those Rice or Pasta sides, depending on the family size, and I make some sort of cookies. Then, on the way to their house, we stop at the store and get 1-2 rotisserie chickens, a bag of salad and bottle of dressing, and some fresh fruit (watermelon if it's in season, otherwise something like grapes, oranges, etc). A lot of times I'll also make some muffins or get some bagels, so they have a little more "something" for the next day.
Ideally, yes, I'd make homemade dinner.... but our church is going through a "baby season" where it seems like everyone and their sister is popping one out, and this is the more convenient route for me.
