Peel the cucumber and grate it on the large holes of a box grater. Sprinkle with 1 teaspoon of salt and let stand for about 20 minutes to help draw out moisture from the cucumber
Wrap the grated cucumber in a clean kitchen cloth and wring as much water as possible. Discard the water.
In a medium bowl, combine drained cucumbers, Greek yogurt, grated garlic clove, olive oil, vinegar, lemon juice, and finely chopped dill. Season the sauce with salt and pepper.
Make lemon rice:
Finely chop garlic (preferably with a knife and not a garlic press). Heat the olive oil in a medium pot over low heat. When hot add the garlic and cook for 30 seconds until fragrant.
Add the rice and cook, stirring, for about 30-60 seconds, until all the rice grains are coated in oil.
Add oregano and chicken broth, close the pot with a tightly-fitting lid (preferably transparent so you can see when the rice starts to boil), bring to a boil then reduce the temperature to low and cook for 14 minutes. Take the pot off the heat and leave it (covered) to rest for 10 minutes.
Fluff the rice with a spatula or wooden spoon and season with lemon zest, lemon juice, parsley, salt, and pepper. Stir gently until combined.
Make quick cucumber tomato salad:
Peel the cucumber and cut into 1/2-inch cubes, cut tomatoes also into cubes. Dice red onion, chop parsley, slice olives.
Add all the ingredients for the salad to a bowl and stir until combined. Season with salt and pepper.
Cook the chicken:
Cook the chicken breasts in half horizontally so that you have thinner fillets (you can also pound them with a meat tenderizer). Add to a bowl with 1 tablespoon of oil, lemon juice, lemon zest, garlic powder, and oregano. Season with salt and pepper. Stir to coat and leave to marinate for 15-30 minutes.
Remove the chicken from the marinade. Dredge in flour on all sides.
Heat the remaining tablespoon of oil over medium-high heat in a frying pan. Cook chicken fillets in batches, until browned on both sides and cooked through in the center.
Remove from the pan, let rest for at least 5 minutes then cut into slices.
Assemble:
Divide cooked chicken breast, cucumber tomato salad, lemon rice, and tzatziki dip between 4 bowls.
Enjoy!
