Heat the oil in a large, shallow pan. Toss in the onion and garlic and fry for 1-2 minutes until soft. Add the mince and stir fry for a further 3-4 minutes until browned.
Tip the tomatoes into the pan and stir in the tomato purée and cinnamon, then season generously with salt and pepper. Leave the mince to simmer for 20 minutes, adding the chickpeas half way through.
Add the goat's cheese and mint over the mince. Serve with toasted bread.
