Roasted Cauliflower, Israeli couscous, pine nuts and raisins

The wife pointed out
this recipe for roasted cauliflower with Israeli couscous, pine nuts and raisins. It's seasoned with salt, pepper, turmeric and the giant couscous is briefly sauteed in olive oil and then cooked in chicken stock. I think it's a new "desperation dinner" for us. The longest step is roasting the cauliflower which takes about 20 minutes at 425F. The recipe also called for fresh parsley or cilantro; all I had to use was dried parsley. I'll fix that next time. Trust me, it's better than it looks. Recipe reprinted in case the link goes dead:
1 small cauliflower
4 cloves garlic, crushed
3 Tbs olive oil
1 onion, peeled and chopped
1 tsp turmeric
1 1/2 cups giant couscous (also called Israeli couscous) or fregola
2 1/2 cups chicken stock
sea salt and freshly ground black pepper
1/2 cup toasted pine nuts
1/4 cup currants
1/2 cup chopped fresh coriander or parsley
1. Preheat oven to 170C. Cut cauliflower into small even-sized florets and place in an oven pan. Combine the crushed garlic with 2 tablespoons olive oil, pour garlic oil over the cauliflower and toss well to coat. Roast for 30 minutes or until the florets turn golden brown, stirring occasionally to allow for even cooking. Remove to cool.
2. At the same time, heat a saucepan, add 1 tablespoon olive oil and the onion and cook over a moderate heat for 5-10 minutes until softened but not coloured. Stir in the turmeric and giant couscous and cook for 1 minute, stirring continually.
3. Add stock and bring to the boil, then turn down the heat and simmer for 8-10 minutes, stirring regularly until the grains are tender to the bite and all the liquid has been absorbed. Season with salt and pepper to taste.
4. Stir through the roast cauliflower, pine nuts, currants and coriander or parsley and serve.

UpdateI prepared this with the other half of the cauliflower several days later. The only change I did was cook the giant couscous with boiling stock (like risotto). Still, the couscous had a fairly tough/al dente feel to it, identical to cooking it with cold stock. However, when the leftovers were heated up, I was told the couscous was much more tender.
Also, I was told by the proprietor of the market where I bought the Israeli Couscous, I should soak it at least 15 minutes prior to cooking, it would make for a more tender cooked pasta. I think I'll do the soaking next time in hopes of getting the texture of the couscous more tender and uniform. Without soaking, it has a slightly tougher interior than exterior.
