Cook your pasta as directed by your packaging. Rinse the pasta with cold water and drain the water well.
Whisk up your pesto, lemon juice, and vinegar together, adding in your salt and pepper as you whisk. Whisk this up in oil until it is thoroughly blended.
Toss together the vegetables and pasta, adding a drizzle of pesto dressing. Toss this mix together to fully coat it in the dressing.
Refrigerate the dish, covered, for an hour or until it’s cold throughout.
