Yummy Chicken Alfredo/Pesto Tortelloni

My hubby went on a business trip a few years back, and they had a pasta bar at the office he went to where they could pick their own sauces and ingredients to put with their pasta. He loved it! When he got home, he told me about this yummy pasta that he had. This is my attempt at re-creating it!

Mushrooms, sliced
Onion- sliced into thin strips
2 cloves garlic, minced
Chicken, cubed (For the two of us, I usually just do 1 chicken breast or 3 tenders)
2 TBSP oil
1 package of Tortelloni pasta (We like the 3 cheese flavor)
1 package of pesto sauce prepared per instructions
1/2 cup butter
1 cup cream (or fat free half and half works too)
Parmesan cheese to taste

Cook the chicken in a pan with oil. When it starts to brown, add in the vegetables. Saute until done. In the meantime, boil some water. Cook the pasta according to the directions. Drain. In the same pan, melt 1/2 cup of butter. Pour in cream and stir. Add in desired amount of Parmesan cheese to make it taste like alfredo sauce. Pour pasta into the alfredo sauce. Mix in desired amount of pesto. Add chicken/vegetables and stir together. I like to top it with shredded Parmesan. Enjoy!!
