Eggs work in meatloaf to act as a binding ingredient. Flax eggs work in a similar capacity and have the benefit of being vegan and cholesterol-free. To make one "egg", stir together one heaping tablespoon of ground flaxseed with three tablespoons of water (double this to replace the two eggs in this recipe). Let it sit for 10 minutes to thicken, then use in place of the eggs.
