Peel and finely chop the onions, garlic, carrots and celery – don't worry about the technique, just chop away until fine. Halve the red peppers, remove the stalks and seeds and roughly chop. Place your largest casserole-type pan on a medium high heat. Add 2 lugs of olive oil and all your chopped vegetables. Add the chilli powder, cumin and cinnamon with a good pinch of salt and pepper. Stir every 30 seconds for around 7 minutes until softened and lightly coloured.
