Shredded Roast Beef Sandwiches

1 3-4lbs roast beef - I like a chuck roast
3 medium onions sliced thinly
1 8oz can tomato sauce
1/4 cup soy sauce (I use a Phillipine soy sauce not kikoman and the other grocery store brands, they are too over powering for my taste)
1 - 2 cloves garlic, crushed
3/4 cup water

Spray the crockpot with nonstick cooking spray. Add the onions in the bottom, the roast and pour over the other ingredients. Cook on low for 8 - 10 hours.

Remove the roast from the pot. Remove the onions. Drain the broth and put it in the freezer to cool so that the fat will rise and you can skim it off.

Using 2 forks shred the beef. Mix it with the broth and onions.

Line a muffin pan with muffin cups and pack each one full of the beef and onion mixture. Freeze until solid. Place the cups in a large freezer bag. Lable and date the bag. Each muffin cup is 1 serving for a sandwich. Take out the number of servings you need for a meal. Thaw and remove the paper cup. Reheat the meat until it is piping hot.

Fill a fresh bun with the beef and onion filling, add a slice of your favorite cheese. Serve with chips or fries or a steamed vegetable.
