Here's my lame, um I mean easy, recipe for sweet pork similar to what you might find at Costa Vida/ Cafe Rio or any of those big burritto places. It is loosely based on this "real" recipe.
1 pork roast or pork chops , about 4 lbs. (I suppose the cut of meat matters, but I haven't had enough experience)
1 t. powdered onion
1 t. powered garlic
1 can chicken broth
1/4 c fresh cilantro chopped up
2 T soy sauce
1 can of Sprite or other lemon/lime drink
Brown roast in a frying pan. Mix garlic, onion, and cilantro. Pour part of the chicken broth into the crock pot. Put roast into pot and pour rest of chicken broth and soy sauce over it. Pour a little of the sprite over it (about 1/4 c, just give it a quick glurg). Sprinkle onion/garlic/cilantro over top and or rub it in if desired. Cook on low for about 8 hrs or until pork pulls apart easily. (Or do like me and cook on high for about 2 hrs and on low for about 4).
