An alternative to pot roast is to make shredded beef for tacos, enchiladas or fajitas.

What I do is cover the roast with water, season with chili powder, garlic powder, salt, pepper, cumin, oregano and bring it to a boil, then simmer until tender, cool and shread it with a fork.

My favorite is shredded beef fajitas. Lightly brown some onions, green or red peppers - or both, seasoned with salt, pepper, garlic powder, oregano, cumin, add some salsa, hot sauce, add in the the shredded beef, a little bit of the liquid from cooking the roast, simmer for a short while, flour tortillas, cheese, sour cream and diced green chilies ... and oh my. It's an outstanding way of using/cooking "pot roasts" if you like mexican food.
