I keep a can of tuna in the pantry for mornings like last Tuesday, when William announced he needed lunch in five minutes and the fridge was nearly empty. I chopped an onion, put everything in a bowl, and by the time he was done tying his shoes he was Tuna Sandwich Wrapped and ready. He ate a slice in the car and said, “Wait, why does this taste better than the cafeteria version?” Because this simple tuna sandwich recipe softens the onions first, and that 30-second step changes everything. The creamy tuna sandwich filling uses mayo, sweet pickle relish and a little sugar to balance out the flavors.

A quick kitchen memory
Last Tuesday I was running late. William had soccer practice after school, and I didn’t pack anything. I took out a can of tuna, chopped half an onion and put everything in a bowl. She looked over my shoulder and said, “Mom, is that tuna thing again?”
I microwaved the onions for 30 seconds, mixed in the mayo and flavored it, and spooned it out. His face lit up. “Wait, it’s actually really good.”
By the time I finished packing his sandwich, he had eaten two spoonfuls straight from the bowl. I had to make a second batch so I could keep some for myself. The thing about this easy tuna sandwich is that it’s very simple, but it never gets boring.
