Heat the oil in a frying pan. Cook the onion for 12-15 mins until starting to caramelise. Add the chickpeas, cumin and peppers and season well, then cook for a few mins until hot throughout.
Create spaces in the pan for each of the eggs. Crack the eggs into the pan, then cover and cook for 2-3 mins, or until the eggs are done to your liking. Scatter over the feta, lemon zest and mint. Serve alongside the flatbreads, if you like.
