In a large pot over medium heat, toast cumin seeds until fragrant.
Add olive oil, onion, garlic and chilli pepper. Stir-fry until onion is translucent.
Add all remaining ingredients except kale. Cover, reduce heat, and allow to simmer for 25 minutes or so, or until potatoes are tender.
Remove from heat, stir through kale, sprinkle with coriander leaves, and serve with corn chips.
