A savoury flapjack is a mixture of oats, seeds and vegetables baked until crispy. What's not to love? Here we've used carrots, spinach, feta and coriander to give a fresh vibrant flapjack. If you, or your children, don't like seeds then finely blitz them in a food processor before adding to the oat mix. To make this vegan, substitute the feta cheese with a vegan cheese or nutritional yeast. Can be served cold in a packed lunch or warm straight from the oven for a perfect vegetarian meal.
