Little Kid Fruit Salad

Set out:
- a bowl of canned pineapple chunks with the juice (and/or canned peaches or pears)
- a banana (peeled, unless your little kid can do that)
- a butter knife and a cutting board
- a small bowl of mini marshmallows

Your little kid carefully slices the banana, and dumps that and the pineapple and juice into a plastic bowl and then adds the marshmallows. This is best served immidiately, and I'm not actually claiming that it's something that adults want to eat but your kid will be SO proud.
