Portillo’s Chopped Salad with Sweet Italian Dressing

"Ditalini pasta is a tiny tube-shaped pasta. If you can't find it, you can easily sub in another little pasta shape. Even small elbow macaroni would work. You're looking for about 3 cups cooked pasta when it's all said and done. The lettuce is really customizable here. If you buy bagged lettuce that already has red cabbage or radicchio in it, you could omit or cut down the chopped cabbage. I believe the original Portillo's salad is a combination of iceberg, romaine and red cabbage.For the chicken, a rotisserie chicken works great here, as well as any other kind of leftover cooked/grilled chicken (the more flavorful, the better!). Keep in mind you could leave the chicken out completely for more of a side dish salad. You could sub in another kind of cheese (experiment with varieties you like) if you aren't a fan of the Gorgonzola. About the vinegar, I like the taste and color of white balsamic vinegar here but regular dark balsamic will work, too, just keep in mind that the dressing will color the salad a bit. I think you could easily use red or white wine vinegar, too.This salad makes the best leftovers. I eat it for days and it makes me so very happy. When I've made it for large group gatherings (entertaining, potlucks, etc), I always toss the entire salad with the dressing, which is ok because there are rarely leftovers. But if it's just for our family, I add dressing to each portion so that I can store the dressing and salad separately (keeps the leftovers fresh and non-soggy)...."
