Just Eggs, or another plant-based egg substitute, is my favorite option to use in place of an egg wash when frying. Because the consistency is so similar to eggs, this really helps your bread stick to the food. You can find this at most grocery stores near the eggs. Ground flax seeds (or flaxseed meal) whisked with water also make a good egg wash substitute for frying. This mixture is also known as flax eggs. You’ll want to do about 2.5 tablespoons of water for every tablespoon of flaxseeds. The thickness and slightly sticky texture of this mixture make a good binding agent, and they don’t have much of a taste, so it will not affect the flavor
