Preheat your oven to 425°F and peel your sweet potatoes before chopping them into 1/2-inch cubes. Spread them out on a large sheet pan ensuring enough space between each piece to promote even roasting rather than steaming. Drizzle with olive oil, sprinkle on paprika, garlic powder, salt, and pepper, then toss everything together until well coated.
While your sweet potatoes are roasting, prepare your quinoa according to package instructions. Once cooked, allow it to cool down naturally or hasten the process by spreading it out on a sheet pan and placing it in the freezer for about 15 minutes.
Zest your lemon until you have about one teaspoon of zest before juicing it to obtain three tablespoons of fresh juice. Combine all dressing ingredients—zest, juice, apple cider vinegar, mustard, oregano, dried basil, honey, minced garlic—into a mason jar and season with salt and pepper as desired.
In a large bowl, combine coarsely chopped spinach with your cooled quinoa. Add in your roasted sweet potatoes alongside chopped avocado pieces, dried cranberries, and optional basil if using.
Only dress portions of salad that will be consumed right away by tossing them gently with desired amounts of prepared dressing. Adjust seasoning with salt as needed before enjoying promptly once dressed.
