Slice fennel bulb, oranges, olives, and red onion according to ingredient notes above. Save 1/3 of one of the oranges to make your dressing.
In a small sauce pan, add vinegar, fresh squeezed orange juice from 1/3 of an orange, chopped basil, salt & pepper and simmer for 2 minutes. Place in fridge to cool.
I layered the salad, starting with spinach, then fennel, then oranges, then red onion, then olives, and drizzled the orange vinaigrette (OIL FREE) over the salad.
