Cooking Instructions
- Preheat the oven to 210C / fan 190C / gas mark 7. Cut the sweet potatoes into fries (peel optional). Place on a lined baking tray and toss with 1 tsp oil and a pinch of sea salt. Roast for 20-25 mins, until soft and golden.
- Finely dice half the onion. Finely chop or crush the garlic. Roughly chop the sundried tomatoes and half the sunflower seeds. Heat a large frying pan on medium heat. Add the sunflower seeds and toast for 2-3 mins, stirring regularly, until golden.
- Add 1 tbsp oil, the onion, garlic, sundried tomatoes and half the harissa to the pan. Cook for 3-4 mins, until softening. Add the flour, mix and cook for 2 mins, then remove from the heat.
- Drain and rinse the lentils, then add to the frying pan. Season generously with sea salt and mix. Form the lentil mixture into 4 burgers. Place on a lined baking tray and bake for 12-15 mins, until heated through.
- Thinly slice the avocado. Squeeze over the lime juice and season with sea salt to taste.
- Serve the mixed salad on plates, drizzled with the maple mustard dressing. Serve alongside the fries, avocado and lentil burgers.
