Now that the weather in the US seems to be really heating up, do you have any unconventional 'cold food' recommendations?

I worked outside much of the day in 90°+ heat. I was thinking to getting a chopped salad from Subway, but went to the grocery for a few items. I spied a container of Campbell’s Slow Cooked New England Clam Chowder and thought, “Now that might be good cold!” A little doctoring and it was a great cool meal paired with a fresh tomato, smoked Swiss cheese (now at Aldi!) and Dijon/mayo blend. My only regret is I forgot the chipotle Cholula in the soup.
