Spinach - Mushroom Salad

This is one of our very favorite salads. I've been making this for 17 years. This has been requested as our salad on Thanksgiving.

8 slices bacon, cooked & crumbled

Wash spinach and pat dry.
Tear into bite size pieces.
Combine spinach, mushrooms, eggs and green onions in large bowl.

Top spinach with dressing just before serving. Sprinkle with bacon on top.
