This is an easy pantry recipe; just use what you have. Most of the ingredients are easily interchangeable and can be swapped with whatever you have around: russet potatoes for the red or yukon; baby spinach for arugula; goat, feta, or blue cheese for the parmesan; kalamata for the green Spanish olives; herbs of your choosing for the green onions. Savor the possibilites. —warmhearth
