We also grab a bag of any pasta, boil it then drain it in and run cold water to help cool it down. Add diced ham, or chicken, minced green and red peppers, red onions, garlic (if you like) and add in some olive oil with balsamic vinegar and toss. Around our place it goes quickly.
We also take cucumbers sliced them about 1" thick use a melon baller to removed about 1/2 the seeds in the center and then add some soft cream cheese (we use the ones that have herbs added to them) that goes in the center of the cucumber.
