Bring a large pot of well-salted water to a rolling boil over high heat.*It is important to use well salted water in order to season the pasta. This is the best opportunity for seasoning the pasta.
Once the water is boiling, add the pasta to the pot. Cook the pasta according to the package instructions until it reaches a soft texture, but still has a slight firmness to it. Aim for about 2-3 minutes past al dente as the pasta will firm up a bit when cooled.
When the pasta is cooked to the desired doneness, carefully drain it into a colander to remove excess water.
If the pasta you are using directs you to rinse the pasta, give it a quick rinse under cold water.
Transfer the drained pasta to a baking sheet lined with parchment paper or a silicone mat. Toss with 1-2 tablespoons of olive oil and spread the pasta out into an even layer to allow it to cool for about 5 minutes. This helps prevent the pasta from clumping together.
After 5 minutes, while the pasta is still warm, add it to a large mixing bowl along with ¼ of the salad dressing and toss to combine. The pasta will absorb the dressing best while it is still warm, which yields an extra flavorful salad.
Once the pasta has cooled the rest of the way, about 10-15 minutes, add your remaining salad ingredients, such as vegetables, proteins, herbs, and dressing (reserve about ¼), and toss everything together until well combined.
For best flavor, chill for at least 30 minutes to allow the flavors to blend. Toss with the reserved dressing and serve.
