Pat the diced chicken breast completely dry with paper towels to remove excess moisture. This helps the chicken develop a golden, flavorful crust instead of steaming during cooking.
Place the chicken into a large mixing bowl and drizzle with olive oil. Add the smoked paprika, garlic powder, onion powder, salt, and black pepper. Toss thoroughly until every piece is evenly coated. Let the chicken marinate for 10–15 minutes if time allows for deeper flavor.
Heat a large nonstick skillet over medium-high heat. Once the pan is hot, add the seasoned chicken in a single layer, leaving a little space between the pieces. Cook undisturbed for about 4–5 minutes until the bottom develops a golden-brown crust.
Flip the chicken pieces and continue cooking for another 4–6 minutes, stirring occasionally, until they are fully cooked and the internal temperature reaches 165°F (74°C).
Transfer the cooked chicken to a clean mixing bowl. Immediately pour the buffalo sauce over the hot chicken and gently toss until every piece is evenly coated with the sauce. Allow the chicken to rest for about 5 minutes before assembling the bowls.
While the chicken is resting, cook the brown rice if needed and prepare the vegetables. Dice the cucumber and avocado, halve the cherry tomatoes, shred the carrots, finely dice the celery, and slice the green onions.
Divide the warm cooked brown rice evenly among four serving bowls, spreading it across the bottom to create the base of the meal.
Spoon an equal portion of cottage cheese beside the rice in each bowl rather than mixing it in, allowing everyone to combine it as they eat.
Arrange the buffalo chicken evenly over the rice, making sure each serving receives a generous amount of chicken.
Add the cucumber, cherry tomatoes, shredded carrots, diced celery, and avocado around the chicken, arranging each ingredient in colorful sections for an attractive presentation.
Sprinkle the sliced green onions over each bowl, then squeeze fresh lemon juice evenly across the entire dish to brighten the flavors.
Finish with your favorite optional toppings such as freshly cracked black pepper, chopped parsley, crumbled blue cheese, pumpkin seeds, sunflower seeds, everything bagel seasoning, or an extra drizzle of buffalo sauce or hot sauce if you enjoy additional heat.
Serve immediately while the buffalo chicken is warm and the vegetables remain crisp. For the best flavor, gently mix everything together before enjoying so each bite includes the spicy chicken, creamy cottage cheese, fresh vegetables, and rice.
