Here is a really satisfying meal you can feel good about serving! This recipe replaces traditional pasta with healthy and delicious fresh zucchini noodles, so you can indulge in it often without any guilt. All'arrabbiata is a spicy Italian red sauce made with red pepper flakes. It is traditionally served with rigatoni or penne noodles, but here it is paired with crisp-tender spaghetti-like zucchini noodles. If you’d like to save a little time, you can use prepared arrabbiata sauce. However, you can make your own from scratch in less than half an hour or you can make large batches in advance, and freeze the rest for easy weeknight meals.
