Slow Cooking Soup

My absolute favourite kitchen appliance is my slow cooker. I had an older one which only had 2 heat setting, high and low. Unfortunately I dropped it and the ceramic part shattered. When that happened I immediately went on a seach for a new one. I wanted one with a bigger capacity and with timed settings as well. I found one on sale at Walmart for $28!!! Oh what a day!
My first time using this new slow cooker was a dream come true. I made Vegetable Beef Soup. Hubby and I loved it and the kids...well no so much.
Anyway here is the recipe

1 onion diced
2 carrots chopped
1 stalk celery chopped
2 potatoes cubed
1 can diced tomatoes with juice
1 pound stewing beef cut into 1/2 inch cubes
1 cup frozen green beans
4 cups water
beef bouillon seasoning cube

add all ingrediants to the slow cooker. turn on high for 4 hours or low for 8. YUMMM
