Remove 5 basil cubes from the freezer and allow them to thaw ahead of time. This could take close to an hour depending on the temperature of your kitchen.
Cook your chicken if necessary. I usually purchase a small rotisserie chicken and pull the meat off to save time. This recipe uses the meat of about one full small chicken
Boil a pot of water for your pasta, and cook pasta according to instructions.
Dice your onion and cook in a bit of olive oil over low heat for about 3 minutes - just enough time to caramelize a bit.
Chop the bell pepper
Optional: tomato and mozzarella are a great addition to this dish! Chop them into pieces about the size of the pasta you're using.
Combine the thawed pesto, olive oil, and salt in a small dish and mix well.
Combine all ingredients in a large bowl and stir gently. Remember, if you're adding cheese let the pasta and chicken cool off beforehand.
Refrigerate until you're ready to serve!
