1. Cook the tortellini according to package instructions. Drain and rinse with cold water.
  2. Add tortellini to a large bowl. Add cooked corn, black beans, bell pepper, avocado, cherry tomatoes, onion, and cilantro.
  3. Combine all of the dressing ingredients in a resealable jar. Shake until combined. Pour desired amount of dressing (you may not want to use it all) over the pasta and toss to coat.
To make ahead: Make the dressing and refrigerate. Make the pasta salad separately and store in an airtight container. Add dressing to pasta salad when ready to eat.
