These recipes offer the best of summer and fall. A light, Greek-style shrimp salad and a dish of spiced drumsticks with zesty avocado and tomato salad satisfy in the warmer months, while heartier fare like ravioli stuffed with butternut squash and a sausage hash with potatoes and apples whet your appetite for fall. Whatever the weather, these recipes are quick to prepare, so they work for a family meal or a casual supper with friends.
