This simple Pesto Pasta Salad is loaded with pasta shells, fresh pesto, salty bacon, crumbly feta, juicy tomatoes, and crunchy cashews!
*To roast cashews: preheat oven to 300 degrees F. Place cashews on an unlined, rimmed baking sheet. Roast in preheated oven until cashews are fragrant and golden, about 4-8 minutes. Stir halfway through to avoid burnt spots.
