Bell Pepper Egg in a Hole

2 teaspoons olive oil
​1 bell pepper (any color), cut into four 1/2-inch-thick rings 
4 large eggs 
Coarse salt and ground pepper 
2 teaspoons grated Parmesan

In a large or nonstick skillet, heat 1 teaspoon oil over medium-high. Add bell pepper, then crack 1 egg into the middle of each pepper ring. Season with salt and pepper and cook until egg whites are mostly set but yolks are still runny, 2 to 3 minutes. Gently flip and cook 1 minute more for over easy. Sprinkle with Parmesan and serve!
