I don't really have a "recipe"
I just do whatever veggies I want - usually cucumber, broccoli, onions or green onions, cherry tomatoes halved, diced carrots. Whatever I feel like that day. Then I also add in some shredded cheese, maybe half a bag or so. I pour a 16 oz bottle of italian in w/ cooked to al dente and cooled w/ cold water box of rotini (regular or tricolor) and my veggies (usually like, 1/2 - 3/4 of a cucumber, chopped small, a small broccoli head chopped small, 1 bunch green onions sliced up, 1 container cherry tomatoes) and mix well. You can eat this right away but it is best if gets to marinate for a few hours or overnight - if marinating overnight you should wait to put the tomatoes in until the next day so they don't get mushy. It is best with the full fat italian, but I use the light sometimes (not the fat free, doesn't work right). Also sometimes it needs a bit more dressing later. I just go by taste.
