Martha prepares a simple, organic meal of purple rice and chicken Colombo.
Place rice in a medium saucepan along with 1 3/4 cups water. Bring to a boil over high heat; immediately reduce to low heat. Cover and let simmer for 20 minutes. Remove from heat and keep warm.
Meanwhile, heat oil in a large skillet over medium-high heat. Add onions and garlic and cook, stirring, until golden brown. Add tomatoes, chicken, and sprinkle over curry powder; season with salt and pepper. Reduce heat to low, and cook, stirring, until mixture has thickened and chicken is cooked through, 15 to 25 minutes. Add coconut milk and stir until well combined; cook 5 minutes more. Sprinkle over cinnamon.
Divide rice evenly among 4 serving plates; top with chicken mixture. Garnish with cilantro and serve immediately.
