These Mexican-inspired tacos are high in fibre and very filling. This healthy dish is low in phosphate, potassium and salt.


1 red onion, cut into thin strips

1 red pepper, cut into thin strips

2 tablespoons olive oil

200g tin of sweetcorn in water

½ teaspoon smoked paprika

400g tin black beans in water

2 garlic cloves, grated

½ teaspoon ground cinnamon

½ teaspoon ground cumin

Black pepper

50g cherry tomatoes, quartered

1 spring onion, thinly sliced

5g fresh coriander, chopped

¼ teaspoon hot chilli sauce

2 limes

1 small avocado, ripe

8 mini tortilla wraps

1 fresh chilli, thinly sliced (optional)


  1. Step 1

    Preheat oven to 180C/gas mark 4 and line two baking trays with greaseproof paper. Put the sliced onion and red pepper into a bowl. Add one tablespoon of oil, season with pepper and mix. Spread the vegetables onto one of the trays.

  2. Step 2

    Drain the sweetcorn and pat it dry. Pour it into a bowl, season with pepper and the smoked paprika and stir to combine. Spread the sweetcorn onto the second baking tray. Place both trays in the oven for 25-30 minutes, stir midway through, then leave to cool.

  3. Step 3

    Drain and rinse the beans, pour into a bowl and mash with a fork. Heat the oil in a saucepan on a medium heat and add the garlic. Stir for 30 secs, then add the cinnamon, cumin, black pepper, black beans and a little water if needed.

  4. Step 4

    Cook gently for three minutes, then remove from the heat. For the salsa, put the chilli sauce in a bowl and squeeze in the juice of ½ a lime, mix together. Add the tomatoes, spring onions and coriander leaves and mix again.

  5. Step 5

    For the guacamole, halve the avocado and carefully remove the stone. Scoop all the avocado flesh into another bowl, squeeze in the juice of one lime and mash with a fork to a creamy texture. Set aside until serving.

  6. Step 6

    Lay out the tortilla wraps. Top each with a layer of black beans, vegetables and corn and add a little salsa and guacamole. Serve two tacos per person, with a wedge of lime (and the chilli and extra chopped coriander if desired).
