Breakfast Casserole

"This breakfast casserole is the perfect all-in-one dish to serve for brunch. It’s a hearty, flavorful centerpiece that will disappear quickly at your Mother's Day table. Sausage and eggs are a classic combination, and yogurt is the special ingredient that gives this dish its fluffy texture. Cubes of whole grain bread add depth, and scallions round out the flavor. The ingredients can be prepared the night before, so all you need to do in the morning is put the casserole in the oven. Spend more time with your guests this Mother's Day by preparing this make-ahead meal. Everyone will thank you for it...."
