Who says lettuce is banned from pasta salads? Who says pasta salads are limited to drowning perfectly great pieces of pasta in a mayonnaise bath? Not that there is anything wrong with that but I’m generally not a huge fan. To lighten the load, I’ve swapped mayonnaise with pesto and beefed up the salad with crunchy iceberg lettuce and chunks of butternut squash. For additional crunch, add some toasted bread crumbs - perfect for a summer party!
