I have made this many times to serve to guests in the summer season, it is delicious! You can adjust all amounts to taste and double the recipe to serve more than six. Plan ahead the tortellini needs to chill in the dressing for a minumum of 4 hours or up to 24 hours. Don't be tempted to use more than 1 teaspoon (or less) of fresh garlic, or the garlic flavor will overpower the salad, you can use garlic powder in place of fresh, if you are not a garlic-lover then omit completely, this dressing is good even without the garlic! If you want to serve more dressing on the side, then prepare two separate dressings and use one to marinate the tortellini in and one to serve on the side.
