Passing Json Object Server-Side to MVC ViewResult

Hi:

I have an application in which I need to make a Web Service call to another site that returns a DataSet containing the courses that a particular person has taken - say fields CourseId, CourseTitle, DateRegistered.  I would like to use that DataSet to create a table in a ViewResult so that I can display a table of courses that the person has taken.  I have thought of converting the table into a Json object but am still at a loss as to how to use that data to display a table.  Any help greatly appreciated.  Here's what I have so far:

 public ActionResult CheckHcr()
        {
            var viewModel = new CheckHcrViewModel
            {
                FirstName = Request.QueryString["FirstName"],
                LastName = Request.QueryString["LastName"]
            };

            return View(viewModel);
        }

        [HttpPost]
        public ActionResult CheckHcr(CheckHcrViewModel hcrCheckName)
        {
            if (!ModelState.IsValid)
            {
                return View(hcrCheckName);
            }

            String dsJSON = HcrServices.HC_Qualification_Check(hcrCheckName);

            return RedirectToAction("DisplayCoursesTaken", "ManageHcr", new { ????????? });
}

public static string HC_Qualification_Check(CheckHcrViewModel p)
        {
            var hcr = new Service();

            var dsReturn = new DataSet();

            try
            {
                dsReturn = hcr.ws_HDCO_Qualification_CHECK("SecretWebService", "SecretPassword", p.FirstName, p.LastName, p.BirthDate);
            }
            catch (Exception e)
            { Utilities.LogError(e); }

            var  test = JsonConvert.SerializeObject(dsReturn);

            return test;

        }
