Spray slow cooker with nonstick cooking spray and place roast inside.
In a mixing bowl, combine the rest of the ingredients. Pour over roast and cover with lid.
Cook for 4 hours on high or 6-8 hours on low.
Notes
To turn this into a freezer meal:Place all ingredients in a gallon-sized freezer meal bag. Squeeze out as much air as possible and seal bag closed. Place freezer bag into freezer and it will last 60-90 days.When ready to use, spray inside of slow cooker with non-stick cooking spray and dump ingredients from bag into slow cooker. Place the lid on top and cook for 8-10 hours on low heat (you can cook it for 5-6 hours on high heat, but it will not be as tender as cooking it low and slow).
