Slow Cooker Barbecue Beef Sandwiches wtih Coleslaw This is a great sandwich and easy to prepare. I used ground beef as it was the only beef I had, and left out the rice, thought it would be good without it....and added 1/4 cup of teriyaki sauce, with the bbq sause. Yum Yum!!! I just cook it in a large pot on the stove. I loved the crunch of the slaw, tender but still had some good crunch to it. I will be making this again.
