Chili with potatoes

I know, right... potatoes in chili?!?  Always a sucker for a unique recipe, I tried it.  It's actually quite good! In fact, it is my current go-to chili recipe.  I found this one on allrecipes.com as well.  Judge for yourself!

1 lb ground beef
1 onion, chopped
1 can crushed tomatoes (14 oz)
15 oz can kidney beans
2 c water
4 potatoes, cubed
2 1/2 tbls chili powder (less for kiddos)
2 tsp salt

1. In large saucepan over med-high heat, saute ground beef and onions about 5 minutes. Drain fat.  Add tomato, kidney beans, potatoes, chili powder, salt and water.
2. Reduce heat to low and simmer about 30 minutes or until potatoes are tender.
