Place spinach in a large salad bowl, slice the strawberries and onions and set aside.
Place all of the dressing ingredients into a high-speed blender, such as a Vitamix. Blend for a few mins on high until dressing is creamy.
Add the red onion to the bowl of spinach. Splash a few tablespoons of the dressing to the bowl and toss till lightly coated, add more dressing as desired.
Divide the salad between two dishes. Top with strawberries, nuts and edible flowers, if using. Enjoy!
