Pat the chicken breast dry with a paper towel to ensure a crisp, golden sear.
In a small bowl, combine the ground turmeric, sea salt, and black pepper, then rub the mixture evenly over both sides of the chicken.
Heat the extra virgin olive oil in a medium skillet over medium-high heat until shimmering.
Place the chicken in the skillet and sear for 6-7 minutes per side, or until the internal temperature reaches 165°F and the exterior is beautifully golden.
Remove the chicken from the pan and let it rest on a cutting board for 3 minutes before slicing.
In the same skillet, add the minced garlic and halved cherry tomatoes, sautéing for 2 minutes until the tomatoes begin to soften and release their juices.
Toss in the baby spinach and cooked quinoa, stirring constantly until the spinach is wilted and the quinoa is heated through.
Squeeze the fresh lemon juice over the quinoa mixture and stir to combine all the flavors.
Slice the rested chicken and serve it atop the warm quinoa and vegetable base.
