Lemon and parsley sure do add a little something special to anything they're added to, especially when the dish is pure and simple, like with this recipe.
Heat oil in medium pot over medium-high heat. Add garlic and turmeric; stir 1 minute. Add water, lemon zest, and salt, bring to a boil. Remove pan from heat then stir in couscous. Give it a good stir after adding, then cover and let stand until liquid is absorbed, about 5 minutes.
Fluff with fork; mix in parsley and lemon juice. Season with additional salt and lemon, if necessary.
