½cupcrumbled cooked bacon or bacon lardonsoptional
Toss the pasta with the olive oil, cherry tomatoes, and feta. Add about ¼ cup of the herbed mayo and toss until everything is well coated. Add more mayo by the tablespoon if it seems dry. Taste and add salt and pepper as needed, remembering that you will be adding bacon (if you are adding bacon), which will add saltiness and pepperiness.
Just before serving, toss in the bacon if desired.
