For those who prefer a vegetarian version of Chicken Vindaloo, this recipe is for you. Instead of chicken, this dish uses tofu or paneer as a protein source. The tofu or paneer is marinated in a mixture of spices, vinegar, and yogurt, then cooked with onions, tomatoes, and more spices until it absorbs all the flavors. The result is a delicious and satisfying vegetarian curry that is perfect for meatless Mondays or any day of the week.
