Unstuffed cabbage casserole (Crock Pot)

Love stuffed cabbage but don't want to take the time or turn on the oven?  This gives you the flavor without all the work!

1/2 medium head of cabbage, chopped (1 bag of coleslaw mix will work if you are short on time!)
1 medium onion, diced
1 cup minute rice (I use minute brown rice)
1 lb ground beef, pork or turkey
28 oz can crushed tomatoes, tomato puree or sauce
1/4 cup brown sugar
2 Tablespoons lemon juice 
1 Tablespoon worcestershire sauce
1 tsp each:  Salt, pepper, paprika, garlic powder, thyme (If you are using no salt added tomatoes, you might want to increase the salt a bit)

Mix sugar, lemon juice, worcestershire sauce, and seasonings into the tomatoes in a separate bowl.

Put about 1 cup of tomatoes on the bottom of the pot.  Add 1/2 the cabbage, 1/2 the onion, 1/2 cup rice, crumble half the raw meat on top, then cover with 1 cup of the tomato mixture. 
Repeat the layers, topping with what's left of the tomatoes. 

Cook on high 3-4 hours. Stir well before serving.
