Bring 2 pots of salted water to a boil. One pot is for the pasta, while the other is for the corn and just needs a couple inches of water.
Shuck the corn. Once the water for the corn boils, add the corn, cover the pot, and let the corn cook for 4 minutes. Then remove from the pot and let cool.
Cook the pasta according to the instructions on the box. Once the pasta is ready, drain and pour into a large bowl. Pour ½ cup of the salad dressing over the pasta. By doing this while the pasta is warm, the pasta will absorb the flavor from the lemon garlic dressing.
Then dice the rotisserie chicken, and slice the tomatoes in half.
Use a sharp knife to cut the corn off the cob.
Add the chicken, tomatoes, corn, goat cheese, and arugula to the pasta. Add as much extra dressing as you like.
Serve warm or chilled.
