Pat the chicken breast dry and cut into bite-sized cubes.
Heat the ghee in a large skillet over medium-high heat.
Add the chicken cubes to the skillet and sear until golden brown on all sides, then remove and set aside.
In the same skillet, add the diced onion, minced ginger, and garlic, sautéing for 3-4 minutes until the onion is translucent.
Stir in the garam masala, turmeric, sea salt, and black pepper, toasting the spices for 1 minute until fragrant.
Pour in the tomato puree and coconut milk, stirring well to incorporate the spiced aromatics into a smooth sauce.
Return the chicken to the skillet, reduce the heat to low, and simmer for 10 minutes to allow the flavors to meld and the sauce to thicken.
While the chicken simmers, lightly sauté the cauliflower rice in a separate pan until tender.
Serve the creamy chicken over the cauliflower rice and garnish with freshly chopped cilantro.
