Tuna sweet potato jackets

If your standby supper is baked potatoes with tuna, switch to sweet potatoes and a fresh, spicy topping - budget-friendly and low-fat too

Ingredients

• 4 small sweet potatoes (about 200g each)
• 185g can tuna in spring water, drained
• ½ red onion, finely sliced
• 1 small red chilli, deseeded and chopped
• juice 1 lime
• 6 tbsp Greek yogurt
• handful coriander leaves

Method

1. Scrub the sweet potatoes and prick all over with a fork. Place on a microwaveable plate and cook on High for 18-20 mins, or until tender. Split in half and place each one, cut-side up, on a serving plate.
2. Flake the drained tuna with a fork and divide between the sweet potatoes. Top with the red onion and chilli, then squeeze over the lime juice. Top with a dollop of yogurt and scatter over the coriander, to serve.
