Taco Cassarole

We had nearly a pound of leftover taco meat (we'd had friends over and mis-estimated how much we would need), and since it was seasoned I couldn't really use it for anything with a different flavor palate... so I invented this. It was a big hit.
Tastes like tacos!!

Makes a 9x13 pan.
about 20-25min prep time + 15-20min of baking time

1 pound or so of ground meat
2ish cups uncooked rice (I did a mix of white and brown, it made about 5c cooked)
1 can tomato sauce
2 cans diced tomatoes (or 1qt home canned)
1/2 onion, chopped small
1 can black beans (or pinto) (or about 1-2 cups cooked dry beans)
chilli powder, cumin, garlic powder salt and pepper or taco seasoning
about 8 oz cheddar cheese, shredded

If you are cooking your own beans instead of using canned, you will need to prepare them ahead of time since they take hours to cook.
Put the dry rice in a pan with the tomatoes and their juice, and add enough water for cooking (I don't measure, I just pour in water about twice as high as the rice, then let it simmer with the lid off and check it every couple of minutes, stir it, and add more water if it ever runs low).
While the rice is cooking, brown the meat with the seasoning. You can add the onions if you like them cooked. Drain off the grease. Set aside.
As the rice is getting nearly done, add the tomato sauce and mix it in.
Put the cooked rice, meat, onions (if they're not with the meat), beans, and half of the cheese into a 9x13 baking dish, and mix them all up. You can add additional seasoning if you like (I put in about 1 Tbs garlic powder, 1 Tbs chili powder, 1 Tbs cumin, and 1/2-3/4 tsp salt and just a little pepper).
Sprinkle the remaining cheese over the top, and bake at 350 until everything is warm and melted--about 15-20 minutes.
