Recipe using Sadler's Brisket (Sam's Club)

I'm charged with making brisket in 48 hours, my available shopping time is very limited and my Sam's was out of raw. I bought the sliced smoked Sadler's brisket, which is great heated for about 45 minutes right out of the package--so I can always fall back on that if absolutely necessary. But I'm hoping to adapt it to wind up with something like my traditional braised brisket, which is essentially the linked recipe with the inclusion of potatoes and carrots.

Any suggestions on how to best accomplish something approximating the linked recipe working with the pre-cooked meat? TIA.
