Oil of your choice (Olive, vegetable, groundnut all work well) • (approx. 2 packs) Chestnut mushrooms • large red onion • garlic • (approx. 2 cans) Red kidney beans (in a chilli sauce if you prefer) • water • red chilli peppers (to taste) (or you can use bird's eye, or finger chillis if you prefer it with more heat) • Capsicum peppers (I tend to use one red and one yellow) • Smoked sweet paprika • Chilli powder • Ground cumin • Ground coriander •
