In a large bowl, mix together the pasta, romaine, chicken, Caesar dressing, bacon, and parmesan until everything is evenly coated with the dressing.
Add the croutons on top and an extra sprinkle of bacon and parmesan cheese if desired. Serve immediately.*I do not recommend making this pasta salad more than 2 hours in advanace. The lettuce will begin to wilt the longer it sits.
Notes
5 cups of cooked short pasta is about 8 ounces uncooked.
You can boil the pasta ahead of time and then toss it in a little olive oil to help keep it from sticking together. Then chill the pasta in the fridge until you're ready to make the pasta salad.
If you want to make everything at once, boil the pasta, prep the other ingredients, and then drain the pasta once it's cooked to al dente. Run cold water over the pasta to cool it, and then drain well before adding it to the pasta salad.
