Spray a skillet with cooking spray and place over medium heat.
Add tomatoes to the hot skillet and season with garlic powder, salt, and pepper.
In a small bowl, whisk together the eggs, water, and Parmesan; add to the skillet.
Cook about 5 minutes until the eggs are set but still slightly moist, stirring occasionally to scramble.
Meanwhile, toast bread then top with peanut butter.
Serve eggs alongside orange wedges and peanut butter toast.
