This tuna fish sandwich makes a wonderfully filling lunch! Thanks to the use of clean eating ingredients, this is a healthy sandwich recipe, too!
Something about a well-made tuna fish sandwich always reminds me of my school days.

Sitting in the cafeteria, the smell of the cafeteria cleaners wafting off the tables. Enjoying the hum of all those kids piling in with eager expectation, hoping to find their favorite meal in the lunch line. I have such great memories of those school days.
But beg as I might, Mom always packed my lunches instead of giving me lunch money for the cafeteria food. I didn’t know it then, but I should have been more grateful. When I look back now and realize the type of food they were actually serving us, it isn’t pretty. But as a young kid, you just don’t know any different.
However, one of the lunches that I never complained about was a tuna fish sandwich. I love them. The smell, the flavor, the crunch of the onion, and the perfect “full” feeling after eating one. A good tuna fish sandwich is a thing of beauty, and I always appreciate them.
Mini Chef is heading back to school later this month, so I’ll occasionally make tuna sandwiches for his lunch. I’m not sure he will get the same nostalgic memories from them, but at the very least, I know he’ll be eating good food.
Note: If you are not sure about where to find clean mayo, you can either make it at home or look for this brand (affiliate link).
