Of course!! Go classic, by all means, and add a slice of tomato to a piece of bread, top it with the avocado tuna mixture, cover it with cheese and go to down broiling it off. I love getting MORE tuna filling with my tomato base, but there are definitely days I'm feeling I need the extra carbs too. If your kids are a little iffy on the idea, then for sure, put it on their favourite whole grain bread!
