Check off ingredients as you go.

Contains gluten, milk. Check the labels on packaged ingredients:

  • orzo. Most dry pasta is just wheat and water, but some contains egg; check the packet.
  • feta. Some feta is made with animal rennet; check the label if you are vegetarian.
  • black olives. Olives are packed in brine and are salty; rinsing removes some of it.

Cooking steps

  1. Mix 100 g of the Greek yoghurt with a third of the lemon juice, the oregano, half the crushed garlic and the olive oil. Turn the chicken through it, cover and leave in the fridge for at least 20 minutes and up to 12 hours.

  2. Air-fry the chicken in a single layer at 200°C / 400°F for 10 to 12 minutes, shaking once, or roast it on a lined tray at 220°C / 425°F (200°C fan) for 15 to 18 minutes, until charred at the edges and 74°C in the thickest piece.

    Cooked when: 74°C / 165°F in the thickest part. A food thermometer is the reliable way to tell.

  3. Boil the orzo in salted water for 8 to 9 minutes, drain, rinse under cold water and toss it with another third of the lemon juice.

  4. For the tzatziki, coarsely grate 100 g of the cucumber, squeeze it hard in a clean tea towel, and stir it into the remaining yoghurt with the rest of the garlic, the chopped dill and the last of the lemon juice.

  5. Dice the rest of the cucumber and the tomatoes, mix them with the sliced onion, and break the feta into small pieces over the top with the olives.

  6. Pack four boxes with the orzo and chicken on one side and the salad on the other, and spoon the tzatziki into four small separate pots. Leave the chicken and orzo uncovered until the steam stops, no more than an hour, before closing the lids and refrigerating.

The useful detail

Squeeze the grated cucumber hard before it meets the yoghurt. Cucumber is about 95 per cent water, and left unsqueezed it turns the tzatziki into a thin sauce by the second day in the box.

Make it work for you

One serving is A box of chicken, 50 g (dry weight) of orzo, salad and a pot of tzatziki. You can switch to a smaller portion in the ingredients above; it is three quarters of this, and it contains correspondingly less energy and protein. It is an option, not a goal.

  • Quinoa instead of orzo

    Nuttier and keeps its bite longer in the fridge.

    Per serving: about 35 kcal less, about 1 g less protein, about 2 g more fat.

    Allergens: Removes gluten.

  • Turkey breast instead of chicken

    Slightly leaner and firmer; cook to the same 74°C.

    Per serving: about 10 kcal less, about 1 g more protein, about 1 g less fat.

  • Skyr instead of Greek yoghurt

    Thicker tzatziki and a firmer marinade coating.

    Per serving: about the same energy, about the same protein, about the same fat.

Estimated nutrition

Per standard serving, calculated from the ingredients above. Nutrition changes with substitutions, brands and how much oil stays in the pan.

A lunch box where the chicken and yoghurt between them carry over 40 g of protein, with the orzo kept to 50 g so the box does not fill up on pasta.

Show calculation notes

Each ingredient’s weight is multiplied by its USDA FoodData Central values per 100 g. The whole recipe is added up and divided by 4. Raw weights are used for meat, fish and vegetables; beans and lentils are drained weights. All of the oil is counted as eaten. Added salt is not included; sodium from stock, bread, cheese and tinned food is.

Storage and reheating

In the fridge
Cool, cover and refrigerate within 2 hours of cooking. Eat within 3 to 4 days. Keep the tzatziki in its own pot so the salad stays crisp.
In the freezer
The FDA chart gives cooked poultry dishes 4 to 6 months in the freezer for best quality. Freeze the chicken and orzo on their own, and make the salad and tzatziki fresh on the day you thaw a box.
Reheating
Reheat until it reaches 74°C / 165°F, steaming hot throughout.

Checked against US Food and Drug Administration, Refrigerator and Freezer Storage Chart, USDA Food Safety and Inspection Service, Leftovers and Food Safety, FoodSafety.gov, Safe Minimum Internal Temperatures and FoodSafety.gov, Cold Food Storage Chart. UK guidance from the Food Standards Agency is shorter, at two days for most leftovers.
