This is one of my family's favorite summer salads. I Normally just serve it in a bowl, however for a kid's party, I used the watermelon rinds. Just cut the watermelon in half. Scoop out the watermelon balls. Very carefully cut the bottom slightly so it will sit flat. After pouring on the dressing and tossing, place salad back into the watermelon rind "bowls" to serve.
