Citrus Spinach Salad

I had a variation of this salad at a little inn in Santa Maria while at a couple's retreat. I really liked it but thought it was missing something. I created a dressing for it and added strawberries and perfection was reached! This salad is lovely in that its refreshing, easy and has a good dose of happy-fat -- you know the kind of fat that makes you happy not SAD (pun intended)
Anyway, hope you like it!
