Spanish rice casserole

I made this from this recipe on A Year of Crockpotting. It called for a pound of browned meat but I had loads of left over roast turkey from the weekend so I chopped that up and used it instead.

1 lb meat - any kind (browned mince or chopped leftovers)
1 onion, chopped
1 cup brown rice
1 tin chopped tomatoes
1 clove garlic, crushed
Large pinch mixed herbs
salt and pepper to taste
water or stock

Brown your mince if not using leftovers. Add it to the crock pot with the onion, rice, garlic and herbs. Drain the liquid from the tomatoes into a measuring cup and put the tomatoes in the crock pot. Make up the juice from the tomatoes to 2 cups with water or stock and add. Cook on low for 2-4 hours, until the rice is tender. Season to taste.
