Since spinach is a low carb vegetable and paneer is a high fat vegetarian protein, this dish is an excellent indian vegetarian keto option. I would add 1-2 tablespoons of ground nuts (almonds, cashews or macadamia) while making the spinach sauce as well. You can also increase the quantity of heavy cream to 2 or 2.5 tablespoons. Also, use full fat paneer.
