Make the Moong Batter: Blend soaked green moong, green chili, salt, and water into a smooth, pourable batter (similar to pancake batter consistency). Transfer to a bowl and set aside.
Blend the Gravy Base: In a blender, combine tomatoes, paneer, and garlic cloves with a splash of water until completely smooth.
Build the Gravy: Heat oil in a wide skillet over medium heat. Add chopped onions and bell peppers, sautéing until translucent. Stir in red chili powder, garam masala, and salt, then pour in the blended tomato-paneer puree. Bring to a gentle simmer.
Poach the Dumplings: Reduce heat to low. Scoop ladles of the green moong batter directly onto the bubbling sauce, keeping them slightly spaced apart.
Cover & Steam: Cover the skillet with a lid and let it steam on low heat for 8–10 minutes, or until the moong dumplings are fully set and firm to the touch.
Temper & Serve: Heat ghee in a small pan, crackle mustard seeds, curry leaves, and dried red chilies. Pour the hot tadka over the cooked dumplings, garnish with chopped cilantro, and serve warm with chutney!
