Prepare the pearl couscous according to the package directions. Once cooked, let it cool completely.
In a dry pan over medium heat, cook the frozen corn until thawed and lightly roasted, stirring occasionally. Alternatively, grill the corn for added flavor. Let cool completely.
Add all dressing ingredients to a jar, cover, and shake until well combined. Stir if needed to incorporate the honey. Adjust salt and pepper to taste.
In a large bowl, combine the cooled couscous and corn. Add cherry tomatoes, mozzarella pearls, diced avocado, and fresh herbs (if using).
If eating right away, drizzle with dressing to taste (you may not need it all) and toss. If saving some, only dress what you’ll eat now. Enjoy!
