Make the mango salad dressing. Prep the strawberries, avocado, and onion.
Add the spinach, arugula, strawberries, avocado, and red onion to a large salad bowl. Toss with the dressing. Enjoy immediately.
Notes
This salad feeds 2 as an entree and 4+ as a side. Please note that the dressing recipe makes over a cup worth of dressing, so you can easily double or triple the salad and still have some left over.
