Combine stew meat, potatoes, carrots, celery, sweet onion, garlic, beef broth, V8 juice, water and seasonings into the slow cooker.
Cook on LOW for 8 hours.
At 1 hour left to cook, add in the frozen corn and peas. Mix together the cornstarch and cold water in small bowl and add to the slow cooker. Stir everything together, cover with lid and let cook the remaining 1 hour.
** If you are not home and can't add the stuff 1 hour before the cook time is done. Simply add the other ingredients after the cook time is over, cover with the lid, and let it cook for about 30 minutes to help thicken the stew up and soften the frozen vegetables.
You can use 1 lb - 1 1/2 lbs of the beef stew meat. You probably won't find a package of stew meat that is exactly 1 pound, so get one that is between 1 lb and 1 1/2 lbs.
1 1/2 cups of V8 juice is equal to one can of V8.
