Really good - You can make a dressing, but I used the Olive Garden's Italian Dressing and it was very, very good
Other than the amount of tortellini used - I just listed the ingredients - how much would be up to you.

Ingredients

1/2 lb. frozen Tortellini (cooked and drained and cooled)
Red, Yellow and/or Green pepper - diced
Red Onion - sliced thin
Cucumbers - sliced thin
Kalamata Olives - sliced
Fresh mushrooms - sliced
Feta Cheese
Hard Salami - diced
1/2 cup (approximately) salad dressing

Directions

It is a salad - no real directions
I made this salad early in the day and then refrigerated. Lets all the flavors blend.
