The first thing you want to do is take your drained tuna out of the can and place it in a medium sized bowl.
Grab a fork and break up the tuna chunks into tiny flakey pieces.
Next, combine the mayo, capers, diced scallions, black pepper, dried basil, and salt until it become one homogenous mixture. Taste it and see if you'd like to add any more salt. I generally do a little sprinkle. I like to keep it low sodium.
Here is where everything comes together! Grab your baguette (if you like you can toast it but for me, freshly made baguettes are perfect on their own) and drop large dollops of your tuna mixture in to the bread.
Finally, top it off with your favorite toppings. Mine are fresh cucumbers, thinly shaved red onions, a squeeze of lemon, and some tomatoes.
You can serve it will a side salad, a couple of chips, or you do what I do and have a tuna sandwich with a side of another tuna sandwich. Its the perf. combo.
