Wilted Spinach Salad

Fresh Spinach, washed and torn into pieces
Bacon, sliced into 1 inch pieces
Sweet onion, sliced into rings
Fresh mushrooms, sliced
Feta cheese, crumbled
Vinegar

Fry the bacon pieces until crisp. In the meantime, wash the spinach and place in a bowl. Add the feta cheese, onions rings, and mushroom slices. While the bacon grease is still warm, add vinegar to taste. It should not be too sour, but you should be able to taste the vinegar. Pour enough over the spinach to act like a dressing, toss and serve immediately. This salad is not as good once the bacon/vinegar dressing has cooled and the grease has jelled.

You may use blue cheese instead of the feta. Chopped hard-boiled eggs are also good on top.
