Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Slice the chicken breast into thin, even strips to ensure they get crispy while roasting.
In a medium mixing bowl, whisk together the olive oil, lemon juice, minced garlic, cumin, coriander, turmeric, smoked paprika, sea salt, and black pepper.
Add the chicken strips to the bowl and toss thoroughly until every piece is well coated in the spice marinade.
Spread the chicken in a single layer on the prepared baking sheet and roast for 15 to 18 minutes until the edges are golden and slightly charred.
While the chicken is roasting, dice the cucumber, halve the cherry tomatoes, and finely mince the red onion.
Arrange the fresh vegetables on a plate or in a bowl, top with the hot roasted chicken, and finish with a dollop of Greek yogurt and a sprinkle of fresh parsley.
