How to Make It
Bring water to a boil in a small saucepan; stir in uncooked whole-wheat Israeli couscous and golden raisins. Cover, reduce heat, and simmer 12 minutes or until liquid is absorbed. Place couscous mixture in a bowl.
Heat extra-virgin olive oil in a cast-iron skillet over medium-high. Add radicchio, cut lengthwise into quarters, to pan; cook 5 minutes, turning to brown on all sides. Remove from pan; finely chop. Add radicchio, finely grated Parmesan cheese, extra-virgin olive oil, apple cider vinegar, kosher salt, and black pepper to couscous mixture; toss.
