I know I'm in the minority but I am not a fan of homemade mac and cheese. I'm not a huge fan of boxed either but if I had to choose between the two, I pick the boxed.
For some reason, I find homemade mac and cheese to be very greasy and if you're not eating it when it's piping hot, it turns in to a ball of gritty, cold cheese and pasta. No matter who makes it, I never like it.
I do however, love broccoli and cheese with ritz crackers crumbled on top. Now that is good!
ETA: We do not serve mac and cheese at our Thanksgiving dinner. We're just not a mac and cheese kind of family.
