Combine all of the dressing ingredients except the poppy seeds into your blender. Blend until combined. Pour in poppy seeds and pulse to incorporate.
In a small pan, stir together 2 Tbsp. Truvia and walnut halves over medium heat. Stir constantly until sugar melts and sticks to the nuts. Be careful not to burn! Pour onto parchment paper to cool.
To assemble your salad, layer spinach in bowl(s) and top with sliced peaches, strawberries, goat cheese, and candied walnuts.
Drizzle your homemade poppyseed dressing over the top. Serve and enjoy!
