In a small bowl, whisk together the minced garlic, oregano, cumin, paprika, salt, pepper, and half of the lemon juice.
Slice the chicken breast into thin strips and toss with the spice marinade until every piece is well coated.
Heat the olive oil in a large skillet over medium-high heat and sear the chicken until golden brown and cooked through, about 6-8 minutes.
While the chicken cooks, steam the cauliflower rice and mix it with the cooked quinoa in a serving bowl to create a hearty base.
In a small jar, whisk the Greek yogurt with the remaining lemon juice and a pinch of salt to create a smooth, creamy dressing.
Dice the cucumber, cherry tomatoes, and red onion into small pieces to create a fresh Mediterranean salsa.
Assemble the bowl by topping the cauliflower-quinoa base with the crispy chicken strips and the fresh vegetable salsa.
Finish the dish with a generous drizzle of the lemon-yogurt sauce and a garnish of freshly chopped parsley.
