Roast the Peas: Heat a tawa or pan. Add the fresh green peas (washed and dried) and dry roast them without oil. Roast until they get light brown spots. Do not burn them.
Crush the Peas: Once roasted, let them cool slightly. Lightly crush the peas using a mortar and pestle or pulse once in a mixer. Note: You want a coarse texture, not a fine paste.
Temper the Oil: Heat oil in a kadhai or pan. Add mustard seeds and let them splutter. Then, add cumin seeds.
Sauté Aromatics: Add the crushed garlic cloves and sauté until fragrant. Next, add the chopped onions. Sauté until the onions turn translucent (do not brown them too much).
Add Spice: Add the crushed green chillies and mix well.
Cook the Greens: Add the cleaned Methi leaves to the pan. Sauté for about 1 minute until the leaves wilt slightly.
Season: Add salt to taste. Mix well. The salt will help the Methi release its own water.
Combine: Add the coarsely crushed roasted peas to the pan. Mix everything thoroughly.
Steam Cook: Cover the pan with a lid and let it cook on medium heat for 2 minutes. This steam helps the flavours of the Methi and Peas merge.
Final Touch: Open the lid and cook for another minute to dry out any excess moisture. Your Methi Vatana sabzi is ready!
