You have lots of great ideas here. I would be grateful for either - homemade oven ready, sandwiches or a snack package. I think that all sounds great. I also like the idea of some different baked goods like cookies and muffins.
One suggestion for homemade stuff is a label with all ingredients on it. Someone did that once for us and I loved it! But then i am a bit weird about food ... I like to know exactly what's in it... Like if someone gives me a homemade double crust "meat pie " all I can see is the crust... Weirds me out a bit
