Heat the oil in a large, non-stick frying pan. Add the onion and peppers and fry over a medium heat for 8-10 mins until the veg is beginning to soften. Add the garlic, cumin, coriander and paprika and fry for 1 min more. Tip in the tomatoes, spinach and 100ml water and bubble until the spinach has wilted, then lower to a simmer and cook, uncovered, for 10 mins. Season to taste.

Make four indentations in the tomato mixture and gently crack an egg into each one. Cover with a lid or foil and cook over a gentle heat for 8-10 mins, or until the eggs are just set. Uncover, scatter with the fresh herbs and serve.
