Fast food: The Omelet
While popular in restaurants I think the omelet is an overlooked dish when people cook at home. Scrambled eggs is arguably the most foolproof egg dish, but I'd place the omelet as a close second. You can make an epic omelet like the one above in about 10 minutes.
I like to use 3 eggs when making mine because that just coats my entire cast iron pan. Get your pan extremely hot. I like to use cast iron because it distributes the heat evenly across the whole pan and is perfectly flat. Add 1 or 2 tablespoons of butter or ghee. While the butter heats add your eggs and a bit of salt to a mixing bowl and beat. Chop up whatever vegetables or meat you'd like to add to the omelet. If you're adding meat make sure it’s already cooked as your omelet isn't going to sit on the burner long enough to cook meat. When the butter is nice and hot, and just before it starts to smoke, dump your eggs into the pan. They should immediately begin to cook. Tilt and rotate the pan to make sure the eggs are spread evenly. The eggs should cook through in about a minute. Add the omelet contents to the pan by putting them on one half of the eggs. Turn off the burner and using a metal or wooden spatula fold the eggs in half, covering the contents.
You'll have just made yourself a nutritious meal in about 10 minutes without any of the junk you'd find in fast food. Now you're learning to eat.
