Ingredients

· 1 large chicken fillet

· Rapeseed oil, for brushing

· 2-3 garlic cloves, crushed

· ½ teaspoon dried oregano

· 2 tablespoons Greek yogurt

· 10 cm piece cucumber, grated

· 2 tablespoons chopped mint

· 2 whole meal pitta breads

· 2 red or yellow tomatoes, sliced

· 3-4 red peppers, deseeded and sliced

Method

Cut the chicken fillet in half lengthways, then cover with cling film and bash with a rolling pin to flatten it. Brush with some oil, then cover with the garlic, oregano and some pepper. Heat a non-stick frying pan and cook the chicken for a few minutes each side. Meanwhile, mix the yogurt, cucumber and mint to make tzatziki. Cut the tops from the pittas along their longest side and stuff with the chicken, tomato, pepper and tzatziki. Poke in a few mint leaves to serve.
