For the sake of something simple I have a nice recipe idea for your viewing pleasure. Looking back I didn't really snap a good picture, so you may have to trust me when I say it turned out very yummy!
1) Can of tuna
2) Black Beans
This was my friends idea [hence the man hand in the picture], and it was a good one! We heated the tuna in a pan with some Tapatio to give it a little flavor, then tossed it all together on a warm tortilla and BAM.
Recommended: Avocado, onion, cilantro, lime juice, sour cream
