While hash browns are cooking, in another skillet, saute onion and add meat, to either cook it or heat it through if it's already cooked.
Fry 4 eggs in a splash of olive oil in another skillet on stove on very low heat until just set. Start them out way low & leave them that way!
When the hash browns are done, layer ingredients on top of them as follows; meat & onions (use slotted spoon to drain if needed); salsa; eggs (gently layer); cheese. Put temperature on electric skillet at 300 degrees F and cook until cheese is melted and eggs are the way you like them, approximately 5-7 minutes.
