Creamy Pasta Salad

I found this recipe on Mel's Kitchen Cafe and made it as a side dish and WOW was it good! I know you will enjoy it too!

1 12 oz. package tri-color rotini pasta, cooked and drained
3 roma tomatoes, diced
1 can black olives, sliced
¼ cups red onion, finely diced
3/4 cup parmesan cheese
4 tablespoons basil pesto
2/3 cup creamy Caesar dressing
2 teaspoons sauté spice (equal parts black pepper, salt, and garlic powder)
½-1 cup toasted pine nuts(I omitted the nuts because they were too expensive)

Cook pasta and coat with Caesar dressing while warm. Add the rest of the ingredients (minus the pine nuts) and toss. Top with toasted pine nuts. Refrigerate until ready to serve.
