If you're looking for a nutritious and protein-packed option, try making spinach and tofu dumplings. These dumplings are filled with a mixture of sautéed spinach, tofu, garlic, and ginger. Spinach adds a vibrant green color and is rich in vitamins and minerals, while tofu provides a good source of plant-based protein. The dumplings can be pan-fried or steamed, depending on your preference. Serve them with a tangy soy and vinegar dipping sauce for a delightful combination of flavors.
