Prepare the ingredients per the instructions above.
Place the grated potatoes in a clean kitchen towel and squeeze out any excess moisture. Then mix in the cornstarch and season with salt and pepper.
Heat the olive oil in a skillet over medium heat. Once hot, add the grated potatoes, spreading them out evenly in the skillet.
Cook the potatoes for 5-7 minutes on each side, or until they are golden brown and crispy. Remove from the skillet and set aside.
Brew and prepare the coffee to your liking.
In the same skillet, melt the butter over medium heat. Crack the eggs into the skillet and cook to your preference (over easy, sunny side up, etc).
Once the eggs are cooked, assemble the avocado hash brown toast: place the eggs over the hash browns, and sprinkle of cheese.
Serve the avocado hash brown toast with coffee.
