Heat the ghee in a large skillet over medium-high heat until melted and shimmering.
Add the diced yellow onion and sauté for 5 minutes until translucent and soft.
Stir in the ginger paste and garlic paste, cooking for 1 minute until fragrant.
Add the cubed chicken breast to the skillet and brown on all sides for about 5-6 minutes.
Sprinkle the garam masala, turmeric, cumin, sea salt, and black pepper over the chicken and stir to coat evenly.
Pour in the tomato puree and bring the mixture to a gentle simmer.
Reduce the heat to low, cover the skillet, and cook for 10 minutes to allow the flavors to meld and the chicken to cook through.
Stir in the full-fat coconut milk to create a rich, creamy sauce and heat through for 1 minute.
Steam the cauliflower rice in a separate pan or microwave until tender.
Serve the spiced chicken and sauce over the cauliflower rice for a high-volume, clean eating meal.
