In a large skillet, heat olive oil over medium heat. Add the diced onion and bell peppers, cooking until softened, about 5 minutes.
Add the breakfast sausage to the skillet, breaking it apart with a spatula. Cook until browned and fully cooked, about 7-10 minutes.
Stir in the cooked brown rice, garlic powder, onion powder, salt, and pepper. Mix well and cook for an additional 2-3 minutes until heated through.
In a separate skillet, scramble the eggs over medium heat until fully cooked, about 3-4 minutes. Season with salt and pepper.
To serve, divide the sausage and rice mixture into bowls, top with scrambled eggs, and sprinkle with shredded cheddar cheese and fresh parsley if desired.
