Heat 1 tbsp of the olive oil in a large medium pan and add the chopped onions, chopped red bell pepper and potatoes. Cook on a low heat for about 20 minutes until the potatoes are cooked through

Meanwhile, mix the chickpea flour and water together in a bowl with the salt and pepper

Once the potatoes and onions are cooked, add them to the chickpea mix and stir gently to combine.

Add the chickpea mixture and cook on a medium heat for 5-8 minutes until the bottom is cooked.

When both sides are brown and the tortilla is cooked through, cut into slices and serve hot or cold with a green chatny.
