Eggs are cheap, even organic eggs from free-range chickens. They cost me about $3.50 per dozen. Well worth the price.
Here's how I most often make them.
Step 1: Put a non-stick pan over medium-low for about 10 mins. It's best to have the pan warm before you begin to cook.
Step 2: Drop in about 2 tbsp. of butter. Swirl pan until all butter is melted and entire pan is coated.
Step 3. Carefully crack two or three eggs into the pan. I like mine over easy, but do as you please. (My advice: don't cook the yolks through. A runny yolk is one of life's great pleasures.)
Step 4: Pour entire contents of pan into a bowl, break the yolks and mix with the butter. I find the experience utterly delightful, and when I make this my noon meal I'm not hungry again until late in the afternoon.
