Cut the onions, potatoes, carrots, and chicken into bite-sized pieces.
Heat cooking oil in a pot and sauté the onions.
When the onions become translucent, add the potatoes, carrots, and chicken, and stir-fry.
When the ingredients are partially cooked, add water and bring to a boil.
Once it starts boiling, add curry powder and stir well.
When all the ingredients are fully cooked and the curry thickens, turn off the heat.
