Slice the potatoes thinly and place them in a pot. Add enough water to cover the potatoes and bring to a boil. Meanwhile, prepare the seasoning sauce in a bowl.

Once the potatoes are partially cooked, add vegetable oil and the prepared seasoning sauce. Stir well.

Add a small amount of onion and sliced green chili. Optionally, add mushrooms, carrots, and green onions for extra flavor.

Simmer until the potatoes are tender and the stew thickens.
