I made this today in the slow cooker. I just sliced everything up in the food processor (including meat). I dumped everything in the slow cooker (including sauce mixture). Cooked on low for about 6 hours. It was fantastic!!!! My meat was sliced very thin, if you slice it thicker, I don't know if you would have to cooker longer or not. I just got my grass fed beef order and this was the first thing I made. I really am impressed!!!!
