When dinnertime looms and inspiration is scarce, this pantry pasta will be there for you. Raisins make an unlikely starring appearance; they swell and plump in the pasta cooking liquid and balance the briny intensity of the feta and chile-oil-sizzled olives. (Feel free to skip the anchovies if you want to make it vegetarian.) A handful of parsley to finish and you’ll soon see that you really don’t need to be stocked to be well fed.
