Ragú® Recipe Contest Entry. This family dinner casserole is made with crunchy strands of spaghetti squash layered with a quick simmer vegetarian ragout. It’s made all the easier with Chunky Ragú Sautéed Onion and Garlic Sauce plus cooking the spaghetti squash in the microwave. Tossing the squash strands with crumbled feta and extra virgin olive oil elevates its flavor deliciously. Carrots, celery and zucchini along with the beans simmer into a wonderful veggie protein-filled ragout.
