For the hummus, soak sunflower seeds in almond beverage 2 hr. (or overnight). Reserve 1/2 cup (125 mL) soaking liquid (discard the rest) and drain the seeds.
In blender or food processor, place soaked seeds, reserved soaking liquid, lemon zest, lemon juice, olive oil, garlic, cumin, salt and pepper; pulse until smooth. Hummus can be made up to 3 days ahead and chilled.
Preheat oven to 220˚C (425˚F). Line a baking sheet with parchment paper. Toss together cauliflower and oil. Arrange in single layer on lined sheet. Roast 20 to 25 min., turning halfway through, until tender and lightly charred.
Divide spinach into 4 bowls. Top with roasted cauliflower, chicken, avocado, salsa, hummus and parsley.
Try the hummus as a dip for veggies or it can be drizzled over grilled fish and chicken as a sauce.
