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 potato (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

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.

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.
