Cook your macaroni noodles according to package directions. Drain and rinse with cold water until completely cooled.
In a large mixing bowl, combine the noodles, chopped pickles, red onion, chickpeas, vegan cheddar, and fresh dill.
In a separate bowl or jar, whisk together the yogurt, pickle juice, Dijon mustard, olive oil (if using), garlic powder, salt, and pepper until smooth and creamy.
Pour the dressing over the pasta salad and toss to coat. Taste and adjust salt or pickle juice as desired. For best flavor, let sit in the fridge for at least 30 minutes before serving.
If meal prepping, you can make salad jars, by combining the dressing ingredients in the bottom of 3 to 4 jars, and layering the ingredients in this order: chickpeas, red onion, pickles, macaroni, cheese, fresh dill
