In a medium saucepan, bring the water or vegetable broth to a boil.
Stir in the olive oil, salt, black pepper, and ground cumin (if using).
Remove the saucepan from heat and stir in the couscous. Cover with a lid and let it sit for 5 minutes, allowing the couscous to steam and absorb the liquid.
After 5 minutes, uncover the saucepan and use a fork to fluff the couscous, breaking up any clumps.
Stir in the chopped vegetables and raisins or currants, if using. You can either add them raw or briefly sauté them in a separate pan before mixing them in.
Stir in the chopped fresh parsley.
Transfer the couscous to a serving dish. Garnish with additional parsley if desired.
Enjoy your meal!
