My chilli i use loads of cumin, coriander, some of that lovely smoked Spanish paprika - see what i mean about non authentic! And usually dried chilli.
Grind up those spices, add to sweated onions, peppers and garlic, cook off for a minute or two. Deglaze with some wine or other liquid, then add a tin of tomatoes, plenty of tomato puree.
I usually add three types of bean but normally one is a kidney, maybe a borlotti, haricot... anything.
Usually add chopped mushrooms, sweetcorn. Let it all simmer slowly for a good while. Add anything that you might add to encourage flavour - seasoning and your worcester sauces etc.
Loads of coriander right at the end.
Sometimes have with rice, then maybe in tortillas the next day with some avocado and lime salsa.
