This full-flavored recipe is the result of my mom's love of pasta and our love of cooking together. With a bit of pepper heat and smoky bacon, the entree is excellent alone or paired with grilled chicken. —Lacy Jo Matheson, Sault Sainte Marie, Michigan

"Delicious. Added some roasted cubed chicken to make it a meal."

"Love this recipe for a change of pace. Can be used as main dish (meatless or add chicken), or as a side. Family does not like cherry tomatoes, so I left them out. This is requested often!"

"Flavors of this dish are mmmm.....mmmmm.....good. Worth the trip back to the store to get the forgotten garlic. No balsamic vinegar on hand so I used seasoned rice vinegar."

"This is one of my families favorites and requested often. I love the combination of flavors and that it is easier to reduce or increase the amount depending on the size of the crowd being served. I personally use only 1 tbsp. of olive oil because other wise it feels to greasy to me, but other than that I leave everything the same. This one is worth trying and making!"

"Very tasty recipe, but as other reviewers have noted, I would also reduce the balsamic vinegar. To add another flavor element I would add 1 tablespoon of low sodium soy sauce, increase the red pepper to 1/2 teaspoon, the black pepper to 3/4 teaspoon, and add a bit of grated lemon zest to brighten things a bit. I used whole grain thin spaghetti, which worked well, but would reduce to 10 ounces for a saucier dish. Overall a great recipe & a keeper. Thanks!"
