Basil Chicken Pasta

I had a couple of chicken breasts left over from the night before, so I thought I would whip up a new pasta recipe! There's no such thing as too many pasta recipes! 

Basil Chicken Pasta

1lb chicken breasts, trimmed and cut into bite-sized pieces

2 T olive oil

1 medium onion, chopped 

2 cloves garlic, minced

¼ c balsamic vinegar

2 (14.5 oz) cans Italian style diced tomatoes

12-16 oz uncooked penne (use 12oz if you like a saucier pasta) 

2 T butter

¼ c chopped fresh basil

8 oz fresh mozzarella cut in ½ inch pieces 

Heat olive oil in a large skillet over medium heat; add chicken and onions. Cook until chicken is done.  Reduce heat to med-low and add garlic and balsamic vinegar. Stir to combine. Cook for a minute or two to let the flavors combine. Add tomatoes and their juices. Bring to a simmer and cook for 20 minutes, or until it has slightly thickened. 

Meanwhile, cook pasta according to package directions; drain and return to pot, adding butter. Stir to coat pasta. 

Add basil to tomato sauce and stir to combine. Combine pasta and sauce in a large bowl and toss to combine. Stir in mozzarella cheese and serve immediately.
