Preheat oven to 375°F. In a medium skillet over medium heat, heat the olive oil.
Add shredded potatoes and season with salt and pepper. Cook until potatoes start to get golden brown, about 10 minutes; then add the sun-dried tomatoes and cook for another 2 minutes. Cool mixture off the heat.
In a large bowl, whisk the eggs and dressing together until incorporated. Fold in the potato and sun-dried tomato mix.
Pour the mixture into the pie crust and back for 25–30 minutes, or until the tip of a knife inserted into the center comes out clean. Sprinkle fresh dill and allow to cool, before cutting and serving.
