Drain and rinse chickpeas. Place them on a baking sheet. Use a paper towel to pat them dry.
Slice the sweet potatoes into small half-moon-shaped pieces and place them on the same baking sheet.
Drizzle the olive oil, onion powder, garlic powder and chili powder over the sweet potatoes and chickpeas. Mix to combine and bake for 25 minutes.
To make the dressing, start by putting the olive oil into a small bowl. Whisk continuously while adding in the remaining dressing ingredients. If you need to thin out the dressing, add a small amount of warm water.
Remove the sweet potatoes and chickpeas from the oven, dice the avocado, plate the salad and enjoy! Add a pinch of salt or black pepper if desired.
