I only recently started making couscous when I discovered this Israeli type. I love this stuff, it looks quite similar to acini di pepe, but has a lovely bite and texture quite different from your regular small pasta.
However, it isn't terribly nutritious having no appreciable amounts of calcium or iron, it's basically just pure carbs. But it is a good base to build a dish on. I usually end up with celery, garlic, onion/shallot/leek, fresh parsley, broccoli/cauliflower, zucchini and chicken/pork. I've even used pak choi. Pretty much any fresh veg you add will pair up great. Funnily enough, I've never actually made it plain as a side dish.
I highly recommend trying it out if you're in a rut with your regular starchy side dishes.
