A small bowl, combine paprika, garlic powder, chili powder, salt, pepper, cumin, onion powder, and cayenne. Stir until evenly mixed. I always make sure there are no clumps so the seasoning coats the chicken evenly.
Place the chicken thighs in a mixing bowl and drizzle with avocado oil. Rub the oil into the chicken so it’s fully coated. Sprinkle the spice blend over the thighs and massage it into the meat for maximum flavor coverage.
In a bowl, whisk together olive oil, lime juice, honey, salt, and pepper. Add diced cucumber, avocado, sweet onion, and cilantro. Gently toss everything together, being careful not to mash the avocado. Refrigerate until ready to serve.
Heat your grill to about 400–450°F. Lightly oil the grates to prevent sticking. Place the seasoned chicken thighs on the grill and cook for about 5–7 minutes per side, or until the internal temperature reaches 165°F.
Remove the chicken from the grill and let it rest for a few minutes to retain juices. Transfer to a serving platter and top with the chilled avocado cucumber salad. Serve immediately with fresh lime wedges if desired..
