Easier yet - if you have a hot water dispenser or a Keurig coffee machine kids can make this neat snack or side themselves. We buy whole grain couscous in a box (7.6 oz) and use the 10 oz (large setting) on the Kuerig - yes, less water than package directions but the family wouldn't eat couscous until I made this error with the water which has since become our standard.
Put the couscous in a bowl, 4 cup measuring cup, or any suitable dish, drizzle two or three times around with a good tasty olive oil, add some garlic powder if you like, some pepper - ie., season to taste. Pour in your 10 ounces of water, stir, let sit, covered, for 5 minutes.
In the meantime, finely chop some good feta (honestly, sheep's milk feta is best, not the salty local stuff) and if you like shallots (we do!) finely dice a bit. Dill or cilantro is nice too if it's on hand.
When the five minutes are up, stir in the feta and herbs. Serve. This is so easy, doesn't interfere with cooktop use in making main entree, kids make it for themselves in the afternoon and get a whole grain, nutritious snack!
