For best results, make this salad a few hours ahead so the flavors deepen and the pasta fully absorbs the dressing; if it seems dry after chilling, stir in 1–2 tablespoons of additional mayonnaise or a splash of milk to loosen it up. Finely chopping the vegetables ensures you get a bit of crunch in every bite without overwhelming the tuna, and rinsing the pasta in cold water stops it from overcooking and keeps it from becoming gummy. You can swap peas for corn, add diced bell pepper, or use Greek yogurt for part of the mayonnaise for a lighter version, and always keep the salad well-chilled—especially for picnics—to maintain both flavor and food safety.
