Couscous is a wheat product that cooks in only 5 minutes. You can eat it where ever you'd eat pasta or rice. So you can eat it with stir-fried veggies, baked tofu, or beans. Or you can eat it alone with some spices. No matter how you eat it, couscous sure is convenient.
Wikipedia says this about couscous,
"The couscous available to buy in most Western supermarkets has been pre-steamed and dried, the package directions usually instruct to add it to a little boiling water in a pot and covering for 5 minutes to make it ready for consumption. Another quick and easy method is to prepare it by placing the couscous in a bowl and pouring the boiling water or stock over the couscous, then covering the bowl tightly. The couscous swells and within a few minutes is ready to fluff with a fork and serve. Pre-steamed couscous takes less time to prepare than dried pasta or grains such as rice."
You can even cook couscous in the microwave. Just boil the water in the microwave and add the couscous, let it sit for a few minutes and then fluff it up and eat it.
