Cut Chicken Breast (2 pound) into 1/2-inch chunks.

Add chilis and scallion to the egg mixture and stir to combine. Add in the chopped chicken and mix to combine, then let sit for 5-10 minutes so the chicken can soak up the flavor of the curry and coconut.

Add potatoes in one flat layer on the bottom, then Green Peas (1/2 cup), and lastly pour the Chicken-egg mixture over the top.
Top with Pie Crust (1). Press down on the edges with a fork to seal. Cut slits in the top and brush with the white of the Egg (1).
