The easiest way to prolong a Greek holiday has always been through dinner. A block of feta, a bottle of olive oil, a few tomatoes and suddenly the kitchen is doing a passable impression of somewhere overlooking the Aegean, even if the view outside is considerably greyer.Britons appear increasingly keen to keep that feeling going. New research from Ocado suggests almost a third of us are eating more Greek food than we used to, while searches on its website for spanakopita have risen by 2,605 per cent and those for diced feta by an extraordinary 2,967 per cent year on year. Greek flatbread searches are up 360 per cent over two years, while Greek seasoning has jumped 1,903 per cent.Some of the appeal is familiar. Greece remains one of our favourite holiday destinations, and a quarter of people surveyed said travelling there had encouraged them to recreate its food at home. Health is an even bigger draw: half said they wanted to eat more Greek food because of its reputation for vegetables, pulses, fish, good olive oil and other staples of the Mediterranean diet.“We’re starting to see customers become much more adventurous with Greek food,” says Ocado’s Gia Cazan. “They’re now looking beyond familiar favourites like feta and Greek yoghurt, and are finding new ways to bring other authentic Greek flavours into their everyday meals.”Fortunately, none of that requires a plane ticket. From lamb slowly roasted with lemon, garlic, olives and rosemary to a feta-strewn dipping oil made for dragging warm flatbread through, these recipes bring some of the flavours of a Greek summer to the table – with a crunchy chicken fattoush alongside for good measure.Chicken fattoushCrisp pitta, juicy chicken and plenty of sumac make this a proper summer lunch (Ocado)Fattoush is a Middle-Eastern dish made with crispy chunks of flatbread and chopped vegetables. Here, we've used pitta bread, cucumber, tomato and radish, as well as juicy chicken thighs. Sumac is put to great work too – this ground spice, made from berries, has a distinct tart and zesty character that really takes the flavour of this crunchy salad to the next level. Serves: 4Time: 30 minutesIngredients:9 tbsp olive oil2¾ tsp sumac1 cucumber1 romaine lettuce, shredded1 bunch spring onions, finely sliced1 small bunch parsley, leaves chopped2 pitta breads, or more, if you’re hungy500g chicken thighs6 tomatoes200g radishes, thinly sliced1 small bunch fresh mint, leaves chopped2 lemons, zest and juice½ tsp of sugarMethod:1. Put the chicken thighs onto a plate and drizzle 1 tablespoon of oil over with 2 teaspoons of sumac and some seasoning. Massage this all over the chicken.2. Bring a large non-stick frying pan to a medium heat and cook the chicken for 5 minutes each side.3. While the chicken cooks, halve the cucumber lengthways, deseed with a spoon and cut into chunks. Then quarter the tomatoes, deseed and cut into strips. Add both to a large bowl.4. When the chicken is cooked through, remove from the heat and set aside on a clean plate.5. Add the lettuce, spring onion, radish and herbs to the cucumber and tomato and mix. Next, whisk together the lemon juice and zest, 4 tablespoons of olive oil, ½ teaspoon of sumac and the sugar. Pour this over the salad, tossing well.6. Toast the pitta until just starting to colour, then tear it up. Fry in a non-stick frying pan with 2 tablespoons of oil for 1-2 minutes, sprinkling over ¼ teaspoon of sumac. When the pitta is nice and golden, remove onto some kitchen paper and season well.7. Slice the chicken into strips and add to the salad. Finish by scattering the pitta bread pieces over the top before serving.Greek-style slow-roasted lambLemon, garlic, olives and rosemary do the heavy lifting in this slow-roasted centrepiece (Ocado)Take inspiration from Greece with our slow-roasted leg of lamb recipe.
