Dice the chicken breast into bite-sized pieces and season evenly with the sea salt and black pepper.
Heat the ghee in a large skillet over medium-high heat and sear the chicken until golden on all sides, then remove and set aside.
In the same skillet, add the diced onion, minced garlic, and grated ginger, sautéing until the onion is translucent and fragrant.
Stir in the garam masala, turmeric, and cumin, allowing the spices to toast for about one minute until highly aromatic.
Pour in the tomato puree and coconut milk, stirring well to combine and scraping any browned bits from the bottom of the pan.
Return the seared chicken to the skillet and simmer for 8 to 10 minutes until the sauce has thickened and the chicken is fully cooked.
While the chicken simmers, lightly sauté the cauliflower rice in a separate pan over medium heat for 3 to 5 minutes until tender.
Serve the chicken tikka masala over the cauliflower rice and garnish with fresh chopped cilantro.
