Eggs are a staple food in most people's diet and can be eaten in a number of different ways such as scrambled, boiled, poached and fried. Eggs are also used a lot in baking and are a good binding ingredient. Eggs are full of protein, vitamin A, vitamin D, vitamin B2 and iodine. Did you know that one egg contains six grams of protein so they are a great underrated meat-free source of protein.
