Cook the bacon in a small skillet over medium heat until crispy.
Remove bacon from the skillet and place it on paper towels. Once cool, break into crumbles.
Heat the leftover couscous in the same small skillet with the bacon grease, and cook, stirring occasionally, for 2-3 minutes.
Meanwhile, steam the egg in a small saucepan with a few inches of water and bring to a boil over medium-high heat.
Add a poaching cup that has been coated with butter or olive oil cooking spray.
Crack an egg into the cup, making sure not to break the yolk.
Cover with a lid and cook for 3-4 minutes, or until the egg white is cooked through but the yolk is still soft.
Immediately remove the poaching cup from the pan of water.
To serve, place the couscous into a bowl. Sprinkle with bacon. Place the poached egg on top, followed by a sprinkling of Parmesan cheese and fresh parsley. Season with sea salt and freshly cracked black pepper, to taste.
