My mom made this one for my sister-in-law's bridal shower... it was a hit! She made it without the pasta and put it in croissants, but I've also had it as a pasta salad.
1 box pasta, cooked
1 bottle (16 oz.) coleslaw dressing
1 c. mayo
4 c. cooked chicken (cubed or shredded)
1 1/2 c. red seedless grapes, sliced in half
2 c. celery
Whisk together coleslaw dressing & mayo. Mix in everything else. Refrigerate for at least 2 hours (overnight is best). Serve in a sandwich or as a side pasta salad.
