twice a year our church helps out the local shelter by supplying dinners(suppers). The group at church posts a menu and divides it up into meat/veggiesand dessert. Everyone take a part on one day or if it is a costly meal 2 people may split it. In fact this week is our week and I will be making potroast with potatoes and carrots, I will make enough for 1/2 and there is another lady who will make the other half. I usually buy the throw away pans for mine so I do not have to worry about getting them back.
Now if it is a neighbor or friend who has had a loss, I usually make a casserole and deliver it in my usual pan and retrieve it later, unless it was my lasagna that I usually make extra of in freeze in the throw away alluminum pans.
I think one full meal is enough, but then if it is very close friend I may also buy drinks and fruit etc.
If you live near an outlet or if you are lucky enough to catch a sale it is always in good taste to give a Stouffers family size dinner. A friend of mine always bought an extra mac and cheese when she went to the outlet so she was always prepared with a meal when needed. The outlet also has the food service sizes so they can feed a large family or crowd.
Good Luck....
wouldn't it be nice if more neighbors did this for each other? This is becoming a lost art.
