On a cold day there is nothing better then a bowl of chili. I know true chili does not have beans but in Iowa it does. Try this tasty chili with some shredded cheese and Greek yogurt or sour cream on top.
If starting with fresh tomatoes, simmer tomatoes along with onions, garlic, and both kind of peppers. Add salt and chili powder. Let simmer on low until onions and peppers are tender.
If you have an immersion blender use it to just break of the tomato skins a little bit. You don't want to make it smooth. If you use diced tomatoes you may be able to cut your time down and won't need to do this.
Add the browned ground beef, the beans, tomato paste, and brown sugar. Let simmer for as long as you like. The longer it goes the better it gets.
