Cook sausage and hash browns according to package directions. Add any additional seasoning to the hash browns that you prefer, like Italian herbs. Once cooked, add to serving bowls or meal prep containers.
Add eggs and egg whites into a cold skillet. Add butter, place on stove burner, and turn heat to medium-low.
Using a soft spatula (rubber or silicone works best), break the yolks and ensure the eggs are mixed together.
Keep the eggs moving continuously using broad sweeping motions, pushing eggs all the way around the circumference of the skillet, then across the bottom. Continue to push eggs around and across skillet until fluffy and barely set, about 4-5 minutes; they should still look soft and a little runny. Season with salt and pepper in the last minute of cooking.
Remove from heat and add to serving dish.
Top with fresh chives and any other desired toppings.
