Cook the tortellini according to package. Drain, rinse with cold water and refrigerate for about 30 mins.
I buy the already cooked bacon, to save time. For raw bacon, cook until evenly browned. Drain on paper towel and chop into approx. 1/2 inch pieces.
In a large bowl, add the tortellini, chopped bacon, chopped broccoli, halved tomatoes, and chopped onions. Pour the coleslaw dressing over everything and toss to coat all the ingredients. Chill before serving.
I make this the night before and keep in the refrigerator overnight so the flavors blend. It's good the same day you make it, but even better the next day!
