Applesauce is a wonderful whole food snack, if the only ingredient on the list is apples. Look for unsweetened (organic if possible) applesauce. Adding a little cinnamon will flavor it quite nicely, or you can just enjoy it as is. I served it with grapes. As a change, I cut them in half and gave the kids chopsticks. Chopsticks are fun for children to try to use, and cutting the grape gives it a nice flat edge to increase their chances of success with the chopsticks. You could also give them a toothpick to use as something different. Or just stick with a fork. Or fingers.
