Heat the oven to 425 degrees. Mix the carrots with 1 tablespoon of the oil, ¼ teaspoon salt and a grind of pepper. Spread out on a parchment-lined baking sheet and roast for 20 minutes — they should still be a little crunchy.
Place the remaining 2 tablespoons of oil in a large frying pan, over medium heat, and add the onion, caraway and cumin. Fry for 10 minutes, stirring occasionally, until golden brown. Add the chard, cooked carrots, chickpeas, water, ½ teaspoon salt and a good grind of pepper and mix through. Cook for 5 minutes, until the chard leaves are soft and hardly any juice is left in the pan.
Remove from the heat, stir in the lemon juice, top with a generous spoonful of yogurt, a sprinkle of cilantro (or parsley and mint), a drizzle of oil, and a wedge of lemon and serve.
