C.A.
I just did the same thing for a friend of mine, I was lucky enough to have my aunt do it for me too.
What I did for my friend was (yes) lasagna which was made but not cooked (I also made one for us) then I went to Whole Foods and made a salad there and brought the dressing on the said. I bought a loaf of bread and a small thing of fruit from the salad bar and some cookies. The second meal I made for them was chicken teriyaki from Trader Joe's. They have a really good frozen chicken teriyaki that you make in the microwave and I did all the directions but the last heating one, and then I bought frozen Asian veggies and did the same thing with those. Lastly, they have the BEST frozen brown rice that you microwave for about 3 minutes in the bag and just gave that to them frozen.
On an additional note, when I set up a group of people to bring them food the basic rule was that you couldn't go in the house, you have to just drop it off and leave, give them their space.
Enjoy and know that's a wonderful thing you are doing.
