Cut chicken breasts into pieces of about 2 cm (3/4in).
Mix the dry seasoning (garam marsala, curry powder and paprika) and measure 1 tsp of this dry mixture to add to the chicken.
In a bowl, combine the chicken with lemon juice and 1 tsp of the dry seasoning and set aside.
Heat a large frying pan over medium heat and add the olive oil.
Add the chicken pieces and sear for about 2-3 minutes on each side.
Add the butter and once it is melted, add the onion, garlic, and the remaining dry seasoning.
Sauté for about 3 minutes until fragrant.
Add the tomato paste, peas, coconut milk and mix.
When it starts to boil, reduce to low heat, cover pan with a lid and let it simmer on low for 45 minutes stirring occasionally.
Serve with white rice and your favorite veggies.
