The broccoli will absorb the dressing better if steamed or blanched. Mix all ingredients together; add broccoli next to last; just before adding tortellini. Add dressing; I use the entire bottle of dressing. We like the Robusto Italian but it is whatever you prefer. This salad can really be made with whatever vegetable you prefer. I have even used canned chicken or you can use chicken breasts. I do not like raw mushrooms so I omit them. It makes a huge bowl and the longer it sits, the better the flavor is. Refrigerate for at least three hours before serving. DELISH!!
