In a large skillet, heat the olive oil over medium-low. Add the garlic and saute for 1 minute or until fragrant. Add the riced cauliflower and broccoli florets, turn the heat up to medium, and cook for 10 to 12 minutes or until the broccoli and cauliflower are tender and golden, stirring frequently. Remove from heat.

While the broccoli and cauliflower are cooking, make the hemp cheese sauce by adding all ingredients to a blender, and blending on high until smooth. Pour into a medium sauce pan and heat over medium. Stir continuously for 5 minutes or until thickened. As it cooks, you may notice greenish flecks from the blended hemp seeds (totally normal and to be expected with hemp seeds).

Pour the cheese sauce over the broccoli-cauliflower rice, stir, and season with sea salt and black pepper, to taste.
