Braised Pork
Remove the twine and trim the fat from the roast. Cut into 4-5 pieces.
In an oven-safe pot, combine all the ingredients and bring to a boil.
Cover and cook in the oven for about 4 hours, or until the meat is very tender and shreds easily with a fork. Season with salt and pepper.

Using a fork or your hands, shred the meat. Adjust the seasoning and keep warm.

Pico de Gallo
In a bowl, combine all the ingredients.
Season with salt and pepper and let sit for about 10 minutes. Drain excess liquid.
