Preheat the oven to 425 F degrees. Line a baking sheet with parchment paper and set aside.
Place cut sweet potatoes into a bowl and toss with oil and salt. Add to the baking sheet. Bake for about 20 minutes or until cooked through, flipping halfway.
4 cups sweet potatoes, 2 tablespoons olive oil, 1 teaspoon kosher salt
Make the dressing by combining the ingredients to a jar, close the lid and shake together.
¼ cup olive oil, 2 tablespoons apple cider vinegar, 1 tablespoon honey, 1 teaspoon mustard, ¾ teaspoons kosher salt
Remove from the oven and allow the sweet potatoes to cool. (This step can be done ahead of time. Just keep the roasted potatoes in the fridge and complete step 2 the day you want to enjoy the salad.)
Assemble the salad by adding the arugula, red onion, sweet potatoes to a serving bowl and toss to combine with the dressing. Then add in the avocado and pepitas, gently toss together and serve immediately.
