• 4 medium sweet potatoes (weighing about 1kg in total), scrubbed
• 2 teaspoons vegetable oil
• 2 tomatoes, finely chopped
• ½ small red onion or 4 spring onions, finely chopped
• ¼ cucumber, finely chopped
• 4 tablespoons tomato puree
• Ground black pepper

1. Preheat the oven to 200°C, fan oven 180°C, gas mark 6.
2. Slice each sweet potato lengthways into 6 wedges and put them into a roasting tin. Add the vegetable oil and toss to coat. Season with some ground black pepper. Transfer to the oven to roast for 35-40 minutes, or until tender, turning them over after 20 minutes.
3. Meanwhile, make the salsa by mixing together the tomatoes, onion, cucumber and tomato puree.
4. Serve the sweet potato wedges with the salsa on the side.

Tip 1: You could make this with regular potatoes if you like, though they may need a few more minutes in the oven.

Tip 2: Spice up the sweet potatoes by sprinkling them with 1 teaspoon of cumin seeds.
