crock pot mexican pot roast taco meat

This meat turned out to be tender and flavorful.  It's going to make some great tacos.
I adapted the original recipe to suit my need to use a crock pot.

mexican pot roast taco meat (Tyer Florence of the Food Network,) 
2 pounds beef roast
kosher salt
freshly ground black pepper
extra-virgin olive oil
2 cloves garlic, smashed
1 large onion, sliced
1 (28 ounce) can crushed tomatoes 
1 tablespoon ancho chile powder
1 tablespoon cayenne pepper (I omitted because this new mama has 3 little kids who'll be eating this recipe- can I just say that 1 tablespoon is A LOT?  I'd tone it down for my family and we love spice.)
1 tablespoon ground cumin
3 bay leaves

tortillas, cheese, salsa, shredded lettuce, etc.

Season all sides of the beef with a fair amount of salt and pepper.  In a large Dutch oven, heat oil.  Add the garlic and the beef to the pot, browning the meat on all sides.  Add the onion and allow to brown, about 3-4 minutes.  Transfer to a crock pot.  Add the tomatoes plus 1 cup of water, spices, season with salt and pepper.  Cover with a lid and cook on low all day until meat is tender.  Shred meat.  Fill tortillas with the works!
