Preparation
- Preheat the oven to 200°C, fan 180°C, gas 6 and line a baking tray with baking paper. Halve the sweet potatoes lengthways and flatten the bases so they sit flat on the tray. Place cut-side up on the tray and drizzle with the olive oil, rubbing it in so it covers the whole surface. Season and bake for 30 minutes or until soft.
- Meanwhile, drain the tuna and finely chop the spring onions. Put the in a bowl with the mayonnaise and mix well. Season.
- Once the sweet potatoes are cooked, divide the tuna between the 8 halves and scatter over the cheese. Return the sweet potatoes to the oven for 8-10 minutes, until the cheese has melted and is golden. Meanwhile, cook the broccoli in boiling water for 5 minutes, until tender. Serve the tuna melt bakers with the broccoli on the side.
The classic tuna melt sandwich gets a teatime makeover with these meltingly good sweet potato bakers. You can use regular potatoes for this, too, but using sweet potatoes sneaks in an extra one of your 5-a-day.
