Here is a recipe that is just a start, a suggestion.  You can dip tortellini in just about any creamy salad dressing, pesto, salsa. etc..   It is just transportation for the dip.  For something really different try warm browned butter. 

Ingredients:

• 1 package fresh or frozen tortellini (like tri-colored five cheese)
• Dominico’s Dressing
• Magnifico Marinara Dressing
• toothpicks

Directions:

1. Cook tortellini according to package directions (do NOT overcook, best to undercook a bit).
2. Rinse under cold water.
3. Drain well on paper towels.
4. Transfer dressings to small serving bowls.
5. To serve, arrange tortellini on serving platter with toothpicks.
6. Dip in dressings.

To be really fancy:

1. Heat 2 tablespoons oil in large nonstick skillet over medium heat.
2. Add tortellini in batches to oil, cook and stir 3-5 minutes or until lightly golden.
3. Drain on paper towels.

This can also be serves by sticking a toothpick in the tortellini and then sticking the toothpick in a head of cabbage on a plate.

Serves:  How many tortellini in a pound?
