I don't know if anyone else has this issue of what dish to bring something in when you have to take something to someone's house. i usually don't stay till the end of the party.I don't want to bother the host or hostess with, "hey, can I get my dish and wash it out?And can i scoop the leftovers into something else so I can take my dish back?" I spend sometimes more time pondering that than I do what to make. A lot of times I will make something in my glass baking dishes. I will get a cheap aluminum pan from the dollar store and throw it in there and throw it back in the oven to finish, or whatever then, transport it to the other house that way. now I don't have to worry about getting my dish back at the end of the night and they can just store the leftovers and eat them later.
For the next party i'm going to that i am bringing food to,I decided to make cream cheese veggie pizza so I don't have anything to take that in. what I did was buy a festive platter at the dollar store. I am going to cut it into slices and put it on that for transport. this way, the hostess does not have to do any prep on it or worry about what to serve it on. it looks festive sitting on her table for guests. once again, she can keep the platter and throw it out if she pleases.
