Place onions in slow cooker. (I used half of a red onion and half of white because I had them and they needed to be used)
Place roast on top of onions.
Season meat with salt and pepper.
In a small bowl whisk together broth, vinegar, tomato paste, tapioca, garlic and Italian seasoning.
Pour mixture over meat.
Set cooker on low and cook for 8-10 hours. If youre short on time set cooker to high and cook 4-5 hours.
Let cook without disturbing or checking on it; Every time you open the lid it lets all that precious hot air out. I was bummed to come home and find that my lid somehow and fallen in and created a constant leak. But it all worked out just fine in the end.
Once roast is cooked and is tender to the point of falling apart transfer to serving dish.
