Soak one cup of cashews in a bowl of boiling hot water for at least 20-30 minutes.
Preheat oven to 425 degrees F.
On a large rimmed baking sheet, add the garlic cloves, diced sweet potatoes, and chickpeas. Drizzle with 2 tablespoons of olive oil and toss to coat. Next, sprinkle the chili powder, paprika, garlic powder, salt and pepper over the sweet potatoes and chickpeas. Toss well to evenly coat. Transfer to the oven and roast for 20-25 minutes, flipping halfway through, or until the chickpeas are crisp, sweet potatoes are tender and the garlic is roasted and fragrant.
Meanwhile, in a large salad bowl, add the kale and massage with 1 teaspoon of olive oil for a couple of minutes.
To make the dressing, drain the cashews. Combine the soaked cashews, water, lemon juice, roasted garlic cloves and salt in a high power blender and blend until smooth and creamy. Taste and adjust the flavors if desired, adding more lemon juice or salt as necessary.
Add some of the creamy dressing to the kale and toss to coat. Next, add the roasted sweet potatoes and chickpeas in with the kale. Drizzle on some additional dressing and toss to combine. Top the salad with avocado. Serve and enjoy! The salad keeps well for 3-4 days in the fridge; add the avocados just before serving.
