When I made my salad I added the dressing the day before I was going to take it to my craft circle. I found that the pasta soaked up the dressing and wasn't as moist as when I first made it. I would suggest putting everything in a salad bowl except for the dressing and the avocado. Maybe pour 1-2 tablespoons of oil over the pasta to keep it from sticking together and then the day you are serving add the dressing and avocado right before serving.
