Step 1: Wash the greens
Start by thoroughly washing the mustard greens, spinach, and any other greens you are using. Make sure to remove any dirt and chop them roughly. This step will take about 5 minutes.

Step 2: Cook the greens
In a large pot, add the washed greens and enough water to cover them. Cook the greens on medium heat, stirring occasionally, for about 20-25 minutes until they are soft and tender. (Time: 20-25 minutes)

Step 3: Grind the greens
Once the greens are cooked, allow them to cool slightly. Then, either use a hand blender or a traditional stone grinder to mash or puree the greens to your desired consistency. A coarse texture is traditional, but you can blend them smoother if you prefer. (Time: 5-7 minutes)

Step 4: Prepare the tempering
In a separate pan, heat ghee over medium heat. Add cumin seeds and let them splutter. Then, add finely chopped garlic, ginger, and green chilies. Sauté for 2-3 minutes until fragrant. (Time: 3-4 minutes)

Step 5: Add spices
Add chopped onions to the pan and sauté until they turn golden brown. Then, add chopped tomatoes and cook for another 2-3 minutes until the tomatoes soften. Add coriander powder, red chili powder, and garam masala. Stir well to combine the spices. (Time: 5-7 minutes)

Step 6: Combine the greens and tempering
Add the cooked and ground greens to the tempering. Stir everything together well, ensuring the spices and greens are fully mixed. Cook on low heat for another 10-15 minutes to allow the flavors to meld. (Time: 10-15 minutes)

Step 7: Final seasoning
Taste the saag and adjust salt if needed. You can also add a little more ghee for richness. (Time: 1-2 minutes)

Step 8: Serve
Once everything is well combined and cooked through, serve your Sarson Ka Saag hot with makki di roti or any bread of your choice. Enjoy your delicious, nutritious meal! (Total time: 55-65 minutes)
