Keeping Cool

I really need to figure out a way to feed my family this summer using minimal heat. I don't mind running the oven - that's down in my laundry room so it really doesn't heat up the house much. But my stove? It is HOT over the stove!

I am going to try to get my kids to agree to eat more food that are served cold, and preferably with minimal preparation, and that don't cost a lot of money!! I'm still debating the crock pot vs. stovetop thing. I am convinced my crock pot doesn't heat up the kitchen as much, and according to some resources I've seen it really does use a lot less energy than a gas stove, even taking the longer cooking time into consideration...

Ideas welcome!

I only just started a list:
Gezpacho - but some vegetables are very pricey, so we'll have to be creative
Sandwiches (although baking bread does involve some time investment, I don't see myself getting out of this one)
Fresh fruit
Fresh vegetables
Foods I can make in the crock pot

Please share your ideas for summer eating! I'd love it if the focus was on inexpensive ingredients, as well!

Looking forward to hearing your ideas
