In a small bowl, whisk together the olive oil, lemon juice, minced garlic, cumin, paprika, turmeric, coriander, sea salt, and black pepper to create the marinade.
Place the chicken breast in a shallow dish, coat thoroughly with the marinade, and let it rest for 10 minutes.
Heat a non-stick skillet over medium-high heat and sear the chicken for 5 to 7 minutes per side until the internal temperature reaches 165°F and the exterior is golden brown.
While the chicken is cooking, dice the cucumber, halve the cherry tomatoes, and finely mince the red onion.
Remove the chicken from the pan, let it rest for 3 minutes, then slice it into thin strips.
Assemble the bowl by placing the warm cooked brown rice at the bottom, then arrange the sliced chicken and the fresh vegetables on top.
Garnish with a dollop of Greek yogurt and a sprinkle of chopped fresh parsley before serving.
