Preheat the oven to 200°C/180°C fan/400°F. Wash the potatoes and chop the larger ones in half. Pop them into a microwavable bowl and blast them in the microwave on high for 2 minutes (if you don't have a microwave, boil them in salted water for 5 minutes until a knife can cut through them without resistance). Once they are hot and steaming, tip them onto a baking tray and toss with olive oil and salt. Roast for 15-20 minutes until they are golden and crispy.
Meanwhile, prep the other salad ingredients. Chop the cherry tomatoes in half and season with salt. Halve the sundried tomatoes, and thinly slice the spring onion and a few slices of chilli (not too much if you prefer a milder salad!).
Once the potatoes are crispy, arrange everything on your plate. Start with the potatoes and tomatoes, and top with the sun-dried tomatoes. Break off crumbling pieces of goat’s cheese and arrange as much or as little as you wish on top. Sprinkle with spring onion and chilli slivers, a small handful of coriander leaves and enough lemon zest to cover. Drizzle with olive oil and a little salt and pepper.
