Preheat oven to 375°F/190°C/Gas Mark 5.
Brush the oil evenly on the bottom and sides of your 10” skillet (iron preferred, but not necessary).
Spread frozen hash brown evenly across the bottom of the skillet, pressing down a bit.
Cook on stove-top for 10 minutes on medium/high without stirring or moving the hash browns, then transfer to the preheated oven and continue to cook for another 15 minutes.
Meanwhile chop your cooked bacon and stinging nettles, slice your tomatoes in half, and beat your eggs and cream together.
After hash brown crust has finished cooking in the oven, pour the egg mixture evenly over the crust.
Sprinkle the dried minced onions evenly over egg mixture and season with salt and pepper.
Next, layer the chopped blanched stinging nettles (see notes about this), then the bacon, and then the tomatoes.
Bake for 20 minutes or until a knife comes out clean and the egg mixture is not longer runny.
Top with a layer of cheese and back for one more minute.
