Wash the spinach leaves and dal very well and add to a large sized pressure cooker (use at least 6 quart pressure cooker).
Add sliced onions and tomatoes to the pressure cooker.
Add water, salt, turmeric powder and also ginger garlic paste & mix everything well.
Close the pressure cooker with lid and safety valve in position, cook in high until the steam begins to release. Once the steam comes, reduce the heat to low and cook for about 5 to 6 minutes.
Once the cooking is done, switch off the stove and wait for the pressure cooker to cool down.
Meanwhile let us prepare the seasoning. To make the seasoning, heat oil in a pan and lightly fry the cumin seeds.
Also add the broken chilies and minced onions, lightly fry. Now the seasoning is ready, keep this aside.
Once the pressure cooker is cooled, carefully open the lid and see if the dal is cooked and soft.
Mix everything well. If desired, you may add a little more water for the preferred consistecy of dal.
Keep in mind that the dal will further thicken as it cools down, so you may add more water later, if needed.
Add the prepared seasoning to the prepared dal palak curry, gently mix in.
Serve the delicious dal palak with rice or Indian breads like chapathi, poori etc as you like!
