Heart-First tip

In the mood for Mexican? Try this healthy spin on an old favourite – nachos.

Instead of corn chips, replace with delicious baked sweet potato.

Sweet potatoes contain important vitamins like beta carotene, vitamin C, and potassium.

Recent research has shown that regularly eating foods that are high in potassium could help to lower your blood pressure, which is a risk factor for heart disease.

Avocadoes are also high in potassium, along with an abundance of healthy fats and fibre that could also boost heart health.




  1. Step 1

    Preheat oven to 180°C.

  2. Step 2

    Place the sweet potato on a baking tray, lined if needed, and drizzle with olive oil. Cook until discs are crispy.

  3. Step 3

    Mash the avocado and add lime juice and set aside.

  4. Step 4

    In a saucepan or frypan, heat black beans, corn, tomato and zucchini over a low to medium heat. Add spices and stir through. Season to taste with salt and pepper.

  5. Step 5

    Divide mix between bowls and top with spring onion, coriander, avocado and a squeeze of lime juice and serve.
