Cook the rice according to the instructions on the package.
In a pitcher, stir together all coconut-mint mocktail ingredients until well combined. Transfer to the refrigerator to chill until you are ready to serve.
Prep chicken, onion, garlic, ginger, and cilantro per instruction above.
Finish rice: Once tender, season with salt and pepper to taste. Fluff with a fork and cover with a lid.
Heat a nonstick pan over medium heat. Once hot, add the oil, chicken, garam masala, paprika, turmeric, and season with salt and pepper. Saute for 2 to 3 minutes then add the onion, garlic, and ginger. Saute until fragrant, about 2 to 3 minutes longer.
Stir in the broth and tomato paste. Bring to a simmer; let the broth reduce and concentrate in flavor and slightly thicken. Then add in the coconut milk and butter. Continue to simmer until the liquid thickens. Add a bit more tomato paste if needed to help thicken.
Finish the butter chicken: Taste and adjust the seasoning with salt if needed.
Warm naan: Set a pan over medium low heat and warm naan on each side.
Serve: Spoon the rice into a bowl, top with the butter chicken, serve with naan, and garnish with cilantro. Enjoy with the mocktail.
