Soy Free Pasta Salad with Pesto and Roasted Vegetables

This vibrant pasta salad is the kind of dish that earns recipe-card status after the very first bite. Caramelized cherry tomatoes, tender zucchini, and sweet roasted red pepper bring serious depth, while a bright walnut-basil pesto ties everything together with herby, lemony richness. The pesto is blended entirely from whole, recognizable ingredients — fresh basil, raw walnuts, garlic, lemon juice, and olive oil — so there's no need to scan a store-bought jar for hidden additives that could sneak soy into your meal. Whole wheat rotini holds up beautifully to the bold pesto coating, and a handful of peppery arugula folded in at the end keeps the whole bowl feeling fresh rather than heavy. Kalamata olives add a briny punch if you want to take it up another notch. It works equally well served slightly warm right after assembly or chilled the next day, making it a reliable option for meal prep or a crowd-pleasing potluck contribution.
