1 egg, beaten slightly
1/2 cup plain fat-free yogurt

1 1/2 ounces French-fried onions (half a small can)
3/4 cup reduced-fat swiss cheese, shredded (I use Alpine Lace)

Combine all ingredients. Be sure that all moisture is out of spinach.
Pour into pie crust.
Bake at 350 for 40-45 minutes until set. Cover with foil after 30 if crust is getting too dark.
