Place the sliced chicken in a bowl and add olive oil, soy sauce, lemon juice, smoked paprika, garlic powder, onion powder, salt, and pepper. Toss until every piece is coated.
Heat a large nonstick skillet over medium-high heat. When the pan is hot, add the chicken in a single layer. It should sizzle lightly on contact.
Cook the chicken for 4 to 5 minutes without touching it to allow browning. Flip and cook another 4 minutes until golden and the internal temperature reaches 165°F (74°C).
While the chicken cooks, warm your cooked rice or quinoa. Cauliflower rice also works for a low-carb version.
Assemble the bowls by dividing the rice among four bowls. Add tomatoes, cucumber, shredded carrots, and avocado around the edges.
Place the cooked chicken in the center of each bowl.
Drizzle with Greek yogurt or light mayo. For a tangier drizzle, mix yogurt with a squeeze of lemon.
Garnish with fresh herbs and serve immediately or portion into meal-prep containers.
