Heat the coconut oil in your crockpot and add the Garam Masala and cumin seeds, gently heating them until they begin crackle.
Add the tomato puree, coconut milk, ginger, garlic, chili, salt, and pepper, and mix thoroughly.
Give your spicy, coconutty mixture a hearty sniff and then throw in the onions, peppers, chicken, and broth.
Mix, cover, and cook on high for 4 hours or low for 7 or 8 hours.
