Mexican Casserole

I tried this at an Enrichment meeting, but never have made it. I really liked it. You could probably add some corn to it, as well.

1 1/2 cup cracked wheat or pearled barley (if the latter, reduce water by half)
2 tsp. salt
6 c. water

1 1/2 lbs. ground beef
1 onion, chopped, or 1/2 c. dry onions (throw the dry ones it in the above water)

2 tbsp. worcestershire sauce
1/2 c. sliced black olives
8 oz. can tomatoes (do not drain)
3/4 tsp. garlic powder or 1 clove fresh, chopped garlic

1/4 c. water
1/4 c. ketchup

Bring wheat, salt and water to a boil and simmer for 1 hour (barley option - 25 minutes).
Brown beef and onions
Add meat mixture to the cooked wheat, then add worcestershire sauce, olives, tomatoes and garlic.
Place mixture in a 9x13 pan.
Bake 1 hour at 350 degrees.
During last 15 min., mix water and ketchup and drizzle over casserole.
