1Heat the vegetable oil in a large pan over medium heat.
Add the finely chopped onion and sauté until golden brown.
Stir in the minced garlic and grated ginger, cooking for another minute until fragrant.
Add the chopped tomatoes and cook until they soften and the oil starts to separate.
Mix in the ground coriander, ground cumin, turmeric powder, and red chili powder. Cook for 2-3 minutes, stirring frequently.
Add the cubed potatoes and stir to coat them with the spice mixture.
Pour in the water and add salt to taste. Bring to a boil.
Reduce the heat to low, cover the pan, and let it simmer for about 15-20 minutes, or until the potatoes are tender.
Add the green peas and cook for an additional 5 minutes.
Garnish with fresh cilantro before serving.
