Heat your oven to 425°F.
Peel and chop the sweet potatoes into about 1-inch cubes, then toss them in a bowl with olive oil, nutritional yeast, salt, and paprika.
Slice the red onion into strips and place with the sweet potatoes on a baking sheet lined with parchment or a silicone mat.
Roast the veggies for 25 to 30 minutes, until the sweet potatoes are tender and slightly browned.
While the roasted veggies cook, combine the rinsed chickpeas with olive oil, cumin, paprika, garlic powder, and salt in a bowl.
Warm a skillet over medium heat, add 1 tablespoon of oil, then cook the chickpeas, stirring often, for approximately 10 minutes until they are hot and lightly browned.
Remove chickpeas from the skillet and set aside.
In the same pan, add chopped kale (without stems) and cook for about 2 minutes until slightly wilted.
To assemble, place cooked quinoa in a bowl and layer with the wilted kale, sautéed chickpeas, roasted onion, roasted sweet potatoes, sliced avocado, and drizzle with lemon tahini dressing.
