Heat the avocado oil in a large skillet over medium-high heat.
Add the cubed chicken breast to the skillet and season with ground cumin, smoked paprika, garlic powder, sea salt, and black pepper.
Cook the chicken for 5 to 6 minutes until golden brown and cooked through, then remove from the skillet and set aside.
In the same skillet, add the sliced bell peppers, red onion, and zucchini, sautéing for 4 to 5 minutes until tender-crisp.
Return the chicken to the skillet and stir in the cooked quinoa and lime juice.
Toss all ingredients together for 1 to 2 minutes until thoroughly heated through.
Garnish the skillet with chopped fresh cilantro and serve immediately.
