Yum! I wish I could make something like that at my house. But I'd have to cook a second roast for my DW as she can't eat anything even remotely spicy hot.
I'm thinking that your pot roast could be so versatile. One night serve it as a roast, the next, shred it and add a little cilantro and cumin to make it shredded beef for tacos or burritos. If there's any left over, turn that into soup.
Or, just use the leftovers from the original roast to make sandwiches.
OK, now I need to say what I should have said at the beginning of this; What a great idea!
