"This was made for our family's lunch at the pool! In the summer time we spend most of our time together at the pool and BBQ-ing.

Bring a large pot of lightly salted water to a boil. Cook radiatore in the boiling water, stirring occasionally until cooked through but firm to the bite, about 12 to 15 minutes. Drain and rinse under cold water. Soak in cold water for 3 minutes. Drain again.
Combine radiatore, ham, red bell pepper, zucchini, black olives, Cotija cheese, and Greek dressing together in a large bowl; toss to coat.
