Heat the oil in a non-stick pan and fry the pepper for 5 mins until starting to soften. Add the beef, chipotle paste and spices, and cook, stirring, to break down the meat for a few minutes. Stir in the tomatoes, tomato purée, coriander stalks, 150ml water and some seasoning, then cover. Leave to simmer for 20 mins to cook through and reduce a little. Will keep chilled for up to three days, or frozen for up to three months. Defrost thoroughly and reheat until piping hot.

Meanwhile, toss the onions in the lime juice in a bowl and set aside to pickle.

When the mince is ready, warm the rice following pack instructions.

Tip the cooked rice into four serving bowls, then add the beef and top each one with a quarter of the black beans, cherry tomatoes and corn, half an avocado (fan out the slices, if you like), and the coriander leaves. Spoon the pickled onions on top along with any lime juice.
