This Pesto Orzo Pasta Salad is a beautiful welcome to warmer weather. If you use store bought pesto it’s super simple, but if you use homemade it really makes it something special. Just toss a handful of simple ingredients together with a pesto vinaigrette and you’re set. It's a great side dish for a summer bbq or a delicious vegetarian main.
Cook the pasta. Bring a large pot of salted water to a boil and cook the orzo to al-dente (usually a minute or two shy of package directions). Drain and rinse with cold water to cool it down and stop the cooking.
Make the pesto vinaigrette. In a medium sized bowl, whisk together the pesto, red wine vinegar, and kosher salt. Then, while whisking constantly, pour in the extra virgin olive oil in a slow steady stream until emulsified.
Combine all ingredients in a large bowl. Add the orzo, tomatoes, beans, onion, cheese, and arugula to a big mixing bowl. Pour over the pesto vinaigrette and toss to combine.
