ok...a couple suggestions and a couple of questions.
Suggestions:
to best serve this woman and her family,maybe (say you have a bulletin board or such at your church)each group could post weekly their menu of things they are taking to them.(that will help with being bombarded with the same casseroles and meals and such

)
another suggestion is that maybe someone could talk to them and find out some things they like and do not like.Or even some family favorites

Take a childs favorite dessert or a big crock of mac n cheese and some grilled hot dogs or something,make a child(or kids in general)feel special with a meal centered around them.
Another thing to do is try to find a variation on something basic...instead of plain potato salad...look for a ranch one...instead of reg meatloaf make a mexican one...how about a white lasagna with chicken and broccoli,green onion and alfredo as opposed to red.
remember to...everyone gets in the mood for something light and simple...I have a great sub recipe I'll post...that with a bag of chips and a good dip can be enjoyable on the right day and a light simple pocke cake or something...(you could even think theme nights..make a meal to kinda go with a movie you already own maybe you could let them borrow or something)
okay...I'm rambling...I'll go post some recipes for ya...
also....try the "amish macaroni salad" I posted...I juat made a triple batch last week for everyone and they are all already hounding me for more!!!(good stuff)
