Tips and Tricks
Drain the pasta well - Extra water can thin the dressing and make the pasta salad watery. Let the pasta sit in the colander for a minute after rinsing.Cut the vegetables small - Smaller pieces mix better with the pasta and make the salad easier to serve.Taste after chilling - Cold pasta can soften the flavor of the dressing. Add a small pinch of salt or pepper before serving if needed.Use sturdy pasta - Rotini works well because the twists hold the dressing. Avoid thin pasta shapes that break apart after mixing.
Storing
Store in the Refrigerator - Place the pasta salad in an airtight container and refrigerate for up to 3 days.Stir Before Serving - The dressing may settle as it chills. Stir the pasta salad before serving.Add Milk if Needed - If the pasta absorbs too much dressing, stir in 1 to 2 tablespoons of milk to loosen it.
