Arugula and Plum Salad

This salad is stealth delicious. The flavor combination is simple yet perfectly balanced. It is adapted from Fine Cooking.

5 oz. arugula (I also threw in a handful of baby spinach because I had only a 4 oz. bag of arugula)
2 dark plums, cut into wedges
2 T EVOO
1 1/2 T white wine vinegar
good pinch of salt
1/2 red onion, sliced thinly
toasted slivered almonds
crumbled feta

Whisk the EVOO, vinegar and salt in a bowl. Add the red onion and let it macerate for about 10-15 minutes to take the bite out of it. Add the remaining ingredients and toss.
