This sandwich is so good you won't be able to stop eating. I love sweet and spicy foods and I found a way to incorporate this with some canned tuna. My kids love it and it is one of my favorite sandwiches. The fresh pineapple and spicy mayo make this sandwich deliciously good.
Drain your tuna pretty well. Add mayo and mix. Add chopped onions, relish and celery. Peel your pineapple (it has to be fresh. You can use can but it just wont taste the same). Cut the pineapple into rings and take the core out.
In a blender add mayo, lemon juice, chipotle peppers, salt and olive oil blend until well combined. Start toasting your bread (you can use any bread you like).
To assemble sandwiches all you do is slather bread with the spicy mayo onto both pieces. Add as much tuna as you like. I like to make mine fat. Add a ring of pineapple on top with some lettuce and top with the other piece of bread. Cut the sandwich in half or quarters what ever you like. These are great party foods or finger foods.
