What to Make for Dinner on another Hot Day?

So I'm headed to the grocery store to get some stuff we need.  I think I will look for something I can make and serve cold since it's another muggy, groddy day.  I have a squash I will prob cook up for me wiht garlic onions and butter.  I like it that way.  The next squash I'll egg and bread since I think Nick will like it better that way.  So  no huge plans for the day other then shopping and cleaning.  I want to make the house look better for Nick to come home too.  He's got a long week ahead of him so I will buy some apples too, so I can make him an apple pie.  He likes having stuff he can eat easily on his way to work.  So give me some suggestions for a tasty dinner.
