In a small mixing bowl, whisk together the Greek yogurt, smoked paprika, cumin, minced garlic, sea salt, black pepper, and lime juice until smooth.
Place the chicken breast in a shallow dish and coat thoroughly with the yogurt marinade; allow it to marinate for at least 15 minutes in the refrigerator.
Heat the olive oil in a large non-stick skillet over medium-high heat.
Add the marinated chicken to the skillet and cook for 5-6 minutes per side, or until the exterior is charred and the internal temperature reaches 165 degrees Fahrenheit.
Remove the chicken from the pan and let it rest on a cutting board for 3 minutes.
In the same skillet, add the diced zucchini and sweet corn, sautéing for 4-5 minutes until the zucchini is tender and the corn is slightly caramelized.
Slice the chicken into strips and serve it over the warm vegetable sauté, garnished with fresh avocado slices.
