Add the oil, onion, garlic, rice, frozen peas, sausage, and water to your rice cooker. Stir everything everything together and season with a pinch of salt and pepper as desired. Cover and switch to Cook function.
When the rice cooker switches to Warm function, remove the lid, mix the rice with a rice paddle and make 3-4 indentations with the paddle and crack in an egg into each depression. Cover and leave the cooker on warm to set the egg whites and leave the yolks soft.
When the eggs are at your desired level of doneness, carefully scoop each egg out to a plate, fluff the rice again.
Spoon rice into serving bowls and top each bowl with an egg.
As an alternative, you can separately poach or even fry the eggs as desired, and after adding rice to the serving bowls, top each with an egg.
