1/4 cup (1 ounce) Shredded Gruyere Cheese or Grated Parmesan Cheese
Heat a large skillet over medium heat. Add oil to pan. Add leek; cook 8 minutes, stirring frequently. Add potatoes and garlic; cook 15 minutes or until potatoes are tender, stirring occasionally. Stir in 1 teaspoon paprika, 1/4 teaspoon salt, and 1/4 teaspoon pepper. Add chard; cook 4 minutes, stirring constantly.
Using a spoon, push potato mixture aside to make 4 egg-size spaces. Crack 1 egg into each space; sprinkle remaining 1/4 teaspoon salt, remaining 1/4 teaspoon pepper, and remaining 1/4 teaspoon paprika over eggs.
Cover and cook 3 minutes; sprinkle cheese over potato mixture. Cover and cook 2 minutes or until egg yolks are lightly set.
