Low Carb Asparagus Frittata

I found this online and made a couple minor changes to make it even lower in carbs. It is really very, very good!it is very low in carbs.!

Heat olive oil in a 10 inch oven proof pan over medium high heat.

Add onions and salt , and cook , stirring occasionally until softened , about 3 minutes.

Add asparagus , reduce heat and cook , covered until it is barely tender , about 6 minutes.

Pour in eggs and cook until almost set , but still slightly runny on top , about 3 minutes.

Sprinkle cheese over eggs and put in oven to broil until cheese is melted and browned , about 3 minutes.

Remove from oven and slide onto a serving plate.

Cut into wedges.
