Prepare the Beans: Begin by removing the seeds from the fresh bean pods. Rinse the beans thoroughly under running water to clean them.
Cook the Beans: Place the beans in a pressure cooker. Add 1 teaspoon of salt, 1/2 teaspoon of turmeric powder, and 4-5 cups of hot water. Stir to combine everything. Secure the lid and cook on high heat for 10 minutes. Then, lower the heat to medium-low and let it cook for another 15 minutes until the beans are tender but still hold their shape.
Prepare Mustard Greens: While the beans are cooking, wash the mustard greens thoroughly to remove any dirt. Shake off the excess water, let them dry, and finely chop them. Set aside.
Mash the Beans: Once the beans are done, let the pressure release naturally. Open the lid, return the cooker to the stove, and partially mash the beans with the back of a spoon or a masher, leaving some beans whole for texture. If the mixture feels too thick, add a little hot water to achieve a soup-like consistency.
Add Mustard Greens: Add the chopped mustard greens along with salt and mustard oil for a burst of flavor. Mix everything well and cook on medium heat for 3 to 4 minutes until the greens are wilted and perfectly blended with the dal. Simmer for another minute or two so all the flavors come together beautifully.
Final Adjustments: Finally, taste and adjust the salt or consistency if needed.
