In a blender or food processor, puree avocados, spinach, evaporated milk, lime juice and garlic until completely blended.

Pour mixture into saucepan and heat on medium-low. Add in salt, pepper, and cayenne. Taste and add seasonings to taste.

Meanwhile, heat salted water in a large pot and cook tortellini per package directions. Drain water from pasta.

When avocado mixture is warm and heated through, toss with drained pasta and serve with cracked black pepper and shaved parmesan. Enjoy!
