Finely chop the onions, garlic, and ginger, and dice the tomatoes. Set these aside. Wash and peel the potatoes, then cut them into bite-sized cubes.

In a large skillet, heat oil over medium heat. Add chopped onions and sauté for about 5-7 minutes until soft.

Add minced garlic and ginger to the pan. Sauté for an additional 1-2 minutes.

Stir in ground beef and cook for about 5-7 minutes until browned.

Mix in diced tomatoes, cumin, coriander, turmeric, garam masala, and chili powder. Let simmer for 5 minutes.

Add cubed potatoes to the skillet, mix well, and pour in a cup of water. Cover and cook on low for 20-25 minutes.

Taste and adjust seasoning as needed, adding more salt and spices if desired.

Let the dish rest for 10-15 minutes before serving.
