To save time we’ll cook the potatoes, sausage, and eggs simultaneously. Pretend you’re on Iron Chef.
Use the microwave to thaw the spinach. When it's thawed, squeeze out moisture with a clean kitchen towel. Set aside.
Preheat oven to 375°F degrees. Preheat two skillets on the stovetop.
Place the potatoes in a single layer on a baking sheet. Bake, uncovered, for 20 – 25 minutes. Check halfway through and stir the ingredients to ensure even cooking.
In one skillet, crumble and cook the sausage, add the onion about half way through. When cooked, drain excess fat.
Meanwhile, in another skillet cook the eggs mixed with cream, seasoning with salt and pepper to taste. If you don’t use cream, don’t substitute milk for the eggs as it doesn’t freeze as well and your eggs will be watery.
When the eggs are mostly cooked, dump them in with the sausage. Add the thawed and drained spinach and stir to distribute.
Remove the skillets from the heat. By now your potatoes should be cooked, remove from oven and let cool.
Allow everything to cool uncovered to allow some steam to scape.
Once it’s all room temperature it’s time to assemble the bowls.
