Brown the beef in a large pot until cooked.
Add the bell pepper and onion and saute until the onions are translucent. Drain any extra grease.
Pour the tomatoes into a large bowl and squeeze by hand so the chunks are reduced in size.
Add the remaining ingredients (tomatoes, ketchup, kidney beans, garlic, chili powder, and water) to the pot and stir. If you like your chili sweet then use the entire bottle of ketchup, if you prefer it less sweet then use 3/4 of the bottle.
Cook over low with the pot covered for 1 1/2 to 2 hours, stirring occasionally.
