Prepare quinoa according to package directions; set aside to cool.
Combine hummus and lemon juice in a small bowl. Thin with water to desired dressing consistency. Divide the dressing among 4 small condiment containers with lids and refrigerate.
Divide baby kale among 4 single-serving containers with lids. Top each with ½ cup of the quinoa, ½ cup beets, ¼ cup edamame and 1 tablespoon sunflower seeds.
When ready to eat, top with ¼ avocado and the hummus dressing.
