Start by cooking the pasta according to the package directions. Drain and rinse.
While the pasta is cooking, prep the veggies by chopping the yellow onion and sweet potato, and set aside.
Make the dressing by adding the raw apple cider vinegar, olive oil, dijon mustard, garlic powder, oregano, salt, and pepper to a mixing bowl and whisk. Set aside.
Add the cooked pasta, chopped onion, cubed sweet potato, and cannellini beans to a large bowl and drizzle with the dressing. Toss to combine.
Store in the fridge to chill until ready to enjoy.
