Frozen green beans can be used in place of the fresh green beans. Zucchini can be used in place of the yellow summer squash.
Cook the penne and green beans in advance. Toss them with 1 tablespoon of olive oil and place in a resealable food storage plastic bag. Refrigerate for up to 8 hours. Omit the 1 tablespoon of oil when adding the ham and seasoning to the penne and green beans.
Serve this easy penne dish with French bread and flavored sparkling water.
