01 - Rinse the brown rice thoroughly under cold water. Combine the rice, 2 cups of water, and 1/4 teaspoon of salt in a medium saucepan. Bring to a boil over high heat, then reduce the heat to low, cover tightly, and simmer for 25 to 30 minutes until the rice is tender and liquid is absorbed. Remove from heat and fluff with a fork.
02 - In a large mixing bowl, combine the olive oil, 1/2 teaspoon salt, black pepper, smoked paprika, cayenne pepper, and garlic powder. Add the chicken pieces and toss well to ensure the meat is evenly coated with the spice blend.
03 - Heat a large skillet over medium-high heat. Add the seasoned chicken pieces in a single layer. Sauté for 6 to 8 minutes, turning occasionally, until the chicken is cooked through, no longer pink in the center, and lightly browned on the outside. Remove from heat and set aside.
04 - In a small bowl, whisk together the Greek yogurt, Sriracha, lime juice, chopped cilantro, and 1/4 teaspoon salt until the mixture is smooth and fully incorporated. Adjust the heat level by adding more hot sauce if desired.
05 - Divide the cooked brown rice evenly among four serving bowls. Arrange the baby spinach, cherry tomatoes, cucumber, shredded carrots, red bell pepper, and avocado in sections around the rice. Top each bowl with an equal portion of the cooked chicken.
06 - Drizzle the spicy sauce generously over the contents of each bowl. Garnish with toasted sesame seeds, extra fresh cilantro leaves, and lime wedges. Serve immediately while the chicken is warm.
