1. In slow cooker, cook seasoned roast on high for 2 hours turning twice in that period.
2. Add the rest of the ingredients and cook overnight on medium .
3. The longer you cook it the more it will fall apart and be more like shredded roast.
4. Taste and add more seasoning id needed.

Additional Comments:

I have cooked this all day and did everything on medium setting, The only thing I did different is add a little kitchen bouquet for it to brown, which is what happens when you cook it on high, which you can omit
