Stir in the spices: mustard seeds, cumin, and garam masala. Cook for an additional two minutes, allowing the spices to release their flavors. Reduce the heat to low.
Add the spinach, fresh mint. Give it a few stirs until everything becomes well integrated.
Transfer the spinach mixture to a blender and add 1/2 cups of water. Blend until it reaches the desired consistency. I like to leave a bit of texture.
Pour the blended sauce back into the pan and set it over low heat. Avoid overheating so not to burn the spinach, overcooking will darken the beautiful green color.
Stir in the yogurt, lentils, green peas and salt. Taste the mixture and adjust the salt to your preference.
Top it off with a squeeze of lemon for a touch of acidity.
Serve the Emerald Dal with basmati rice and naan bread.
Notes
This dish can be refrigerated for a couple days, but be-ware the bright emerald color will fade after the first day.
