Step 1: chop and fry the onion and garlic in some olive oil till golden
Step 2: add in the cinnamon and cumin and coat the onion and garlic (add pepper now if u want it)
Step 3: after a minute or so add in the lentils and cook for 2 mins, give it a few stirs to distribute onions and spices evenly
Step 4: add in chopped tomatoes, a generous squeeze of purée, beans and chilli powder
Step 5: stir everything well and then add just enough boiling water to cover the lentils, put the lid on the pot and leave it for half an hour or so.
Step 9: I like to serve this with avocado, boiled rice and chopped coriander/cilantro
Step 11: Some more ideas to serve it with are corn on the cob, potato wedges or you could even put it in burritos or something!
