If we are talking easy burritos are an all time favorite. Everyone love Cafe Rio Barbacoa Pork. There are tons of recipes floating around there with TONS of ingredients. My sister Meesha and I have one that is a 2 minute fix.
Cook a pork loin, picnic pork, boneless pork ribs (about 3 pounds)...whatever you can get cheap in the crock pot for 8 hours on low. Shred and add 1/2 cup brown sugar and small can of enchilada sauce (you can use my recipe for homemade enchilada sauce if you want extra credit but then you loose the quickness :). Use for burritos, tacos, nachos, enchiladas, taco salad, whatever. This also freezes well for a quick second dinner.
