Variation
Omit pepperoni. Reduce vegetable cooking time to 5 min. Add 2 cooked and crumbled bacon slices along with the cheese.
Shortcut
To quickly cut the pepperoni into quarters, simply stack the slices before cutting as directed.
Note
If using a very thick pasta sauce, reserve 1/4 cup of the pasta cooking water when draining the pasta. Gradually add the reserved cooking water to the finished dish until of desired consistency.
