Tuna and Artichokes

Leftover burger buns? Warm night? Don't know what to make for dinner? Too late to make anything complicated?  How about tuna and artichoke sandwiches on burger buns?  Two cans of drained tuna, a 14 to 15 ounce can of artichoke hearts, chopped, a little diced celery, black pepper and mayo and you've got 4 hearty sandwiches.
