Preheat the oven to 400F. Line two baking sheets with parchment paper.
Add the sunflower seeds, 1 teaspoon oil, ½ teaspoon salt to one baking sheet. Add the beets, remaining 1 tablespoon oil, and remaining ½ teaspoon salt to the other baking sheet. Toss both to coat in the oil and salt.
Transfer to the oven and bake the sunflower seeds for 5-6 minutes, or until fragrant and lightly toasted. Remove the seeds and continue to bake the beets for about 20 more minutes, or until tender.
In a medium pot, add the quinoa and 1 ½ cups water. Bring to a boil, then reduce the heat to low and simmer, covered, for 12-15 minutes, or until water is evaporated and quinoa is cooked through. Transfer quinoa to a large bowl and spread out to cool.
In a small bowl, whisk together the Sunflower Cream, vinegar, oil, water, mustard, cumin, and salt. Add beets, cabbage, and herbs to the large bowl and pour 1 cup of the dressing over top. Toss to coat. Serve topped with a drizzle of the remaining dressing, ½ cup of the toasted sunflower seeds (save the rest for other meals).
