Preheat oven to 220°C. Pre-make red pepper sauce (if using).
Toss kumara halves on a lined oven tray with a generous drizzle of oil. Season kumara and turn them so they are facing cut-side down. Roast for 30-35 minutes, until golden and tender.
In a bowl, toss tomatoes, cucumber and capsicum with a drizzle of olive oil and red wine vinegar. Season to taste with salt and pepper.
Heat a drizzle of oil in a fry-pan on medium-high heat. Cook chickpeas for 5-6 minutes, tossing regularly, until golden. Add spices and salt to pan and cook a further 1-2 minutes, until fragrant. Season to taste.
Serve spinach topped with kumara, salad, chickpeas and a dollop of coconut yoghurt. Drizzle with roasted red pepper sauce and garnish with dill and toasted seeds.
