When my 17 year old brother passed away suddenly in a car accident, the only thing my mom would eat was the homemade chicken noodle soup that my neighbor made. A co-worker had also brought a tray of deli meats and cheeses and breads which was nice as well. We could snack on them and also put them out if we had people stop by. I know it is terrible, but we wasted so much food during that time period because so many people brought things that we just couldn't eat.
Also, on a side note, we had lots of friends and family at our house leading up to the funeral. After the funeral, nothing. I know people needed to get on with their own lives, and also many didn't know what to do/say, but that was really hard. Just don't forget the family in the weeks and months ahead. A phone call or a short visit (or even getting out of the house to dinner or something) would probably be greatly appreciated.
