Empty tuna, corn, and olives into a large bowl.

Cut your celery stick in half long ways. Then slice each half into small bite size pieces. Toss the celery into your tuna mix

Add mayonnaise to your bowl... Some people like more mayonnaise then others. I personally like to add 5 spoon fulls. I would say after 3 spoon fulls, mix it all up, taste it, and from there you can continue to add more mayo or leave as is, depending on your own personal palette.

Once you have your mayonnaise set to your liking, and salt and pepper to taste. I don't like to add too much, after all, it is for my lil guys :-)

Serve with crackers, on in a sandwich. You can even put a slice of cheese in your sandwich, pop it in the toaster oven, and make yourself a tuna melt. Hope you enjoy! :-)
