"Lights out" Chili

Here's my recepie for chili we had today - I call it "Lights out" chili as that's what usually happens when I make it. We gorge on it and then are forced to take a nap - I don't know if it's because one becomes sleepy with full stomach, or if there's something in chili peppers that makes one sleepy? Anyway, guaranteed to succeed.

1 red onion
1 red chili pepper (adjust according to the hotness of the pepper)
500g minced beef
1 can (400g) of chopped tomatoes
1 can (400g) of butter beans
1 can (400g) of kidney beans
tomato puree
garlic puree
bunch of chopped fresh coriander

Instructions are as simple as you can imagine - fry chopped onion and chili pepper until caramelised, add mince and fry until brown, add rest of the incredients, let simmer gently as long as you have patience to wait. Serve with grated mature cheddar cheese, creme fraiche and nachos.
