Beef stew

This is my mom's recipe and it is serious comfort food for me.

1-2 lbs stew meat
4-6 potatoes, peeled and cubed
1 small bag baby carrots, or 4-6 large carrots, chopped in rounds
2 stalks of celery, chopped into large chunks
1 med. onion
1 can tomato soup
1 packet onion soup mix
Salt and pepper to taste

Mix all ingredients in a large bowl and then transfer to a crock pot. Cook on low for 8-10 hours, or on high 4-5 hours. Serve with crusty garlic bread, and a side salad.
