Grab a frying pan and spray it with vegetable oil. Take three mason-jar (wide mouth) rings turned bottom side up. This way the flat part of the ring is sitting next to the pan surface. Make sure your stove is warm before you add the eggs to each ring. These rings will make your eggs perfectly round. I can usually make three eggs per pan depending, on the size of skillet you are using. Cook on medium heat until cooked. All you do is toast some English muffins, add some cheese and ham or sausage. These are perfect for egg sandwiches.
