Masala Chicken Bites

I don't know if this particular dish has a name, but my MIL just made her own recipe from tasting something at a wedding.

1 lb boneless chicken cut into bite sized squares
Few tbsp sour cream
1/4 tsp black pepper
1/4 tsp laal mirch
1/5 tsp haldi
Salt to taste
Olive oil

Marinate the chicken with the spices and sour cream - a nice coating, not sparse. Heat oil in pan. Add in marinated chicken and let it cook on one side, medium heat, until tender (approximately 10 minutes). I usually cover the pan. Flip and cook again on medium heat for another few minutes, uncovered. Before removing, put heat on high and 'grill' the chicken so it's slightly darkened and has a nice very-cooked-masala residue on one side. Serve as side (goes well with a rice/daal meal). The end product shouldn't be too dry, but not runny either.
