Cooking Instructions
- Preheat the oven to 240C / fan 220C / gas mark 9. Cut the potatoes into thin fries (peel optional). Place onto 1-2 lined baking trays and toss with 1 tbsp oil, a pinch of sea salt and black pepper. Roast for 25-30 mins, until soft and golden.
- Make the quick pickled onion; finely dice the onion and place into a small bowl with the vinegar and a pinch of sea salt. Leave to pickle.
- Heat a medium frying pan on medium-high heat. Add the spinach and a splash of water and cook for 1-2 mins, until wilted. Set aside to cool. Finely chop the parsley. Mix the yoghurt, nutritional yeast, mustard, half the paprika and half the parsley in a bowl. Once cooled, squeeze out any excess liquid from the spinach and add to the bowl. Season with sea salt and black pepper and mix.
- Reheat the pan with 1/2 tbsp oil on medium-high heat. Add the prawns, season with sea salt and cook for 2-3 mins, until almost cooked. Transfer to a small baking dish. Spread the yoghurt mixture over the top. Scatter over the ground almonds. Season with sea salt and black pepper and drizzle with 1/2 tbsp oil.
- Once cooked, remove the fries from the oven. Preheat the oven grill to medium-high. Transfer the prawns to the oven and grill for 6-8 mins, until the almonds are golden brown and the prawns are cooked (keep an eye on the dish to prevent burning).
- Trim the green beans. Wipe the frying pan and reheat with 1/2 tbsp oil on high heat. Add the green beans and cook for 3-4 mins, until cooked.
- Serve the green beans, fries and tiger prawn gratin on plates. Scatter the pickled onion over the veg. Garnish with the remaining parsley and paprika.
