Since nature packages eggs individually, you can easily ramp recipes up or down whether cooking for one or a crowd. Although they are rich in protein and contain a mere 70 calories per egg, they also add fat into your diet -- almost 5 g of it for each egg. Since most of the protein is found in the egg white and most of the fat is in the yolk, keep your potatoes and egg breakfast a bit healthier by using only one yolk for every two to three egg whites.
Peel the potatoes and cut them into 1/2-inch cubes. Make the cubes as close in size to each other as possible to ensure even cooking.
Coat the bottom of the skillet generously with olive oil, and set it over medium heat. Add the potatoes to the pan when the oil begins to shimmer. Cook the potatoes for 5 to 10 minutes, tossing frequently, or until the potatoes are tender and are starting to turn golden brown.
Add the onions and bell peppers, and toss to combine them with the potatoes. Season the vegetables to taste with salt and pepper. Cook for an additional 3 to 5 minutes, stirring frequently, or until the onions are translucent and the bell pepper is soft.
Crack the eggs into a small bowl, and whisk in the milk. Break the yolks so that they are fully incorporated into the mixture.
Pour the egg mixture over the potatoes, and use a spatula or wooden spoon to mix the eggs and the vegetables together. Taste the eggs during the cooking process, and add seasonings if desired.
Cook the egg and vegetable mixture for roughly 3 minutes, or until the eggs are cooked to the desired consistency.
