No other tuna sandwich will EVER compare to this one. It’s super simple but all the flavors come together and complement each other so well. Inspired by my all time favorite tuna sandwich from @gjustabakery!
In a small bowl, combine the tuna, capers and mayo. Season to taste. Spread the olive tapenade onto the sourdough bread then add the tuna mixture. Top with red bell pepper, cucumbers and sprouts. Serve open faced or with another slice of bread as a sandwich.
