- Heat a small nonstick skillet over medium high heat until butter bubbles nicely when you swirl it around.
- If you did not swirl the butter around the pan already, do so now. Add eggs and salt to pan and cook until nicely browned on side facing pan.
- Sprinkle cheeses over half the uncooked side of eggs. Fold the eggs in half, then cook just until cheese has been melted and heated through. Serve.
