Place the chicken breast between two sheets of parchment paper and lightly pound to an even thickness of about half an inch.
In a small bowl, combine the turmeric, smoked paprika, sea salt, and black pepper, then rub the mixture evenly over both sides of the chicken.
Heat the olive oil in a medium stainless steel or cast-iron skillet over medium-high heat until shimmering.
Add the chicken to the pan and sear for 5-6 minutes per side until the exterior is golden brown and the internal temperature reaches 165°F.
Remove the chicken from the pan and let it rest on a cutting board for 3 minutes.
In the same skillet, add the sliced zucchini and minced garlic, sautéing for 3-4 minutes until the zucchini is tender-crisp.
Stir the cooked quinoa into the skillet with the zucchini just to warm it through and absorb the remaining pan juices.
Slice the chicken and serve it over the quinoa and zucchini mixture, finishing with a fresh squeeze of lemon juice.
