Food Storage Chili

I love this chili because it's quick and helps me use up my stored canned foods.  All cans are 15 oz unless otherwise specified.

1 lb lean ground beef
1 large onion
1 can kidney beans
1 can pinto beans
1 can refried beans
1 can corn
1 can chopped tomatoes
1 can tomato sauce
1 cup water
1 4 oz can green chilis
1 pkg taco seasoning
1 pkg Hidden Valley Ranch dressing (NOT buttermilk) dry mix

Chop onion and brown with ground beef.  Add remaining ingredients (don't drain anything).  Bring to boil over medium heat.  Cook for 15 minutes, stirring occasionally.
