Cook Orzo according to package directions. Meanwhile, in a large bowl, whisk together oil, vinegar, oregano, basil, salt & pepper
Drain pasta, rinse with water until cool (I throw in some ice cubes to speed up the process) and drain again. Add to bowl with dressing and gently mix in spinach, tomatoes, olives, feta & (pine nuts) and combine. Add more salt to taste.Serve cold.
