Nana's slow cooker rump roast

OK, truth be told this recipe doesn't come from my grandmother, but while eating it I felt like I was traveling back in time to childhood meals at Nana and David's. Yum! She would be proud of this one, and I bet my method of making it in the slow cooker is so much easier than anything she ever made;) I followed the recipe, so even thought I forgot to include the stick of butter in the photo I did not forge to include it in the sauce. I also added a sliced onion and carrots to the mix for the last two hours of slow cooking. Everyone loved it and wanted more, including Trevor. Bill even agreed that this would be something great to make when we have company. It needs dinner rolls or some cauliflower rice to soak up all that good sauce. I'm excited for the leftovers tomorrow!
