Fry the mince in a frypan with a little oil until brown add the onion. Whilst the mince is browning sprinkle the crushed stock cube into the saucepan and stir.
Empty the tins of tomato and beans into a separate large saucepan. Add the garlic, chilli and capsicum then put the saucepan on a low/medium heat whilst the mince is browning.
Once the mince is added to the large saucepan stir it in. Add the tomato paste, Worcester sauce, paprika and chilli mix.
Season to taste with salt and pepper and add more paprika if required. Leave to simmer on a low heat for 40 minutes to 1 hour. Stir occasionally so it doesn't stick to the bottom of the pan.
Once cooked it can be eaten straightaway, refrigerated or frozen.
