Spicy Tomato Onion Curry

1.Heat the vegetable oil in a deep pan or skillet over medium heat.

2.Add mustard seeds and cumin seeds; let them splutter for about 30 seconds.

3.Add the finely sliced onions and sauté until they turn golden brown, about 8-10 minutes, stirring occasionally to avoid burning.

4.Add the slit green chillies and sauté for another 2 minutes to release their flavor.

5.Add the chopped tomatoes to the pan and cook until they soften and begin to break down, about 8 minutes, stirring occasionally.

6.Sprinkle turmeric powder, red chilli powder, and salt over the tomato-onion mixture; stir well to combine all the spices evenly.

7.Pour in 1/2 cup of water to create a curry base, stir, and bring to a gentle simmer.

8.Cover the pan and let the curry simmer on low heat for 10 minutes, stirring occasionally to prevent sticking.

9.If using, add garam masala during the last 2 minutes of cooking and mix well.

10.Remove from heat and garnish with freshly chopped coriander leaves.

11.Serve hot with steamed rice, roti, or naan bread.
