01 - In a mixing bowl, combine chicken thighs with yogurt, lemon juice, garam masala, cumin, turmeric, chili powder, salt, garlic, and ginger. Stir until chicken pieces are thoroughly coated. Allow to marinate for at least 15 minutes, or up to 2 hours in the refrigerator for deeper flavor.
02 - Rinse basmati rice in cold water until water runs clear. In a saucepan, combine rice, water, and salt. Bring to a strong boil, then reduce heat to low, cover, and simmer for 12 minutes. Remove from heat and let sit, covered, for an additional 10 minutes. Fluff gently with a fork before serving.
03 - While rice is cooking, heat a large skillet over medium-high heat. Add the marinated chicken pieces, cooking for 8 to 10 minutes and stirring occasionally, until golden and cooked through. Remove from heat and set aside.
04 - In a small bowl, whisk together Greek yogurt, lime juice, garam masala, cumin, salt, and pepper. Adjust seasoning as needed for preferred flavor.
05 - In a separate bowl, combine diced mango, sliced red onion, cucumber, red bell pepper, and chopped cilantro. Mix until evenly distributed.
06 - Divide cooked rice evenly among four bowls. Top each portion with sautéed chicken, mango salad, and a generous drizzle of masala yogurt sauce.
07 - Garnish each bowl with roasted cashews and additional cilantro leaves, if desired. Serve immediately.
