Prepare the Spice Mixture: In a medium bowl, whisk together cumin, cayenne pepper, turmeric, coriander, garlic powder, salt, and pepper until well combined.

Coat the Chicken: Rub the spice mixture thoroughly over your chicken breasts, ensuring each piece is evenly coated and let sit for about 10 minutes.

Brown the Chicken: Heat oil in a skillet and cook the seasoned chicken for 6-8 minutes per side until golden brown and cooked through.

Sauté Aromatics: In the same skillet, add onion, jalapeno, ginger, and garlic, sautéing until soft and translucent.

Create the Sauce: Add chopped tomatoes and lemon juice, seasoning with salt and pepper, and cook until the tomatoes soften.

Incorporate Coconut Milk: Pour in coconut milk, stirring to combine, then let the sauce simmer on low heat for 5 minutes.

Combine and Serve: Return chicken to the skillet, simmer for 5 minutes, and garnish with fresh parsley or cilantro before serving.
