Slow Cooker Beef and Barley Soup

One day, when I saw my friend, Jean, she told me she had this dish cooking. It sounded so good, I went home and tried it and have made it three times since! It's easy and so delicious! I even mixed up a batch before going to bed one night, put it on low and in the morning I awoke to a delicious smell. I knew my sister was coming over and would be hungry when she arrived. She loved it!

1 small piece sirloin steak
1 onion
1 carrot
1 stalk celery
1 can or box beef broth
1 small can mushrooms (or fresh, cut up)
Seasoning, if desired

Cut up meat and brown in a small frying pan. Put in 1 1/2 quart slow cooker. Chop onion and brown in same pan before adding to cooker. Cut up carrot and celery and add with broth and mushrooms. Set on low for 8 hours and forget about it! When you come home you'll smell that delightful aroma and feast on a delicious meal! If it's too thick add more broth or eat as a stew!
