STOVE COOKING METHOD
Marinate chicken cubes with all the ingredients in the "chicken marinade". Set aside for atleast 15 mins.
Heat a large skillet/grill pan/ frying pan of your choice at medium high heat on the stove.
Add oil and green chilies. Allow green chilies to change color slightly, takes around 1 mins.
Add marinated chicken, spread out evenly around the pan and leave for 2 to 3 mins without touching or sauteeing.
After 3 mins, when chicken forms a nice sear on one side, start sauteeing for another 2 mins or until chicken looks golden from all sides.
Add peppers and onions. Saute for another 2 to 3 mins or until you reach the desired color of the vegetables you prefer. For a slight char on the edges, 2 to 3 mins is enough.
Turn off flame and adjust seasoning according to your liking. At this stage you can add more lemon juice or chat masala if you like. You can also garnish with more chopped cilantro if you want.
Serve as is, or with a side of yellow rice and plain yogurt, or tortillas or baked potatoes.
