One of my DIL's started giving her kids frozen veggies(corn, peas, green beans, mixed vegetables ). It was warm in her house and part of what the kids liked was the cold nature on a hot day. Now 4 of my kids do this. When the kids get home from school, they go in the frig and get the frozen geggies out. I was amazed.
I had to try the frozen corn and peas too. I actually liked it. My DIL also pulls grapes off the stem and freezes them. The grand kids love them. If I lived in Vegas, I'd grow cherry tomatoes in the back yard where the a/c water comes off the condenser. It will keep the tomatoes watered for free, or at least as long as you use your a/c. You can freeze the cherry tomatoes, and they are good frozen, but not so good if they thaw out.
Hope that helps. Good luck to you and yours.
