Cut the chicken breast into bite-sized 1-inch cubes and place them in a small mixing bowl.
Add the Greek yogurt, turmeric, cumin, sea salt, and black pepper to the chicken, stirring until every piece is evenly coated.
Finely mince the garlic clove and grate the fresh ginger.
Heat the ghee in a large non-stick skillet over medium-high heat.
Add the minced garlic and grated ginger to the skillet, sautéing for 1 minute until fragrant but not browned.
Add the marinated chicken to the skillet and sear for 3-4 minutes, stirring occasionally until the edges are golden.
Pour in the tomato puree and garam masala, stirring to combine with the chicken.
Reduce the heat to medium-low and stir in the full-fat coconut milk to create a smooth, orange sauce.
Simmer the mixture for 5-7 minutes until the chicken is cooked through and the sauce has thickened slightly.
In a separate small skillet, lightly sauté the cauliflower rice over medium heat for 3-4 minutes until tender and moisture has evaporated.
Place the cauliflower rice in a serving bowl and top with the creamy butter chicken.
Garnish with freshly chopped cilantro before serving warm.
