This filling and flavorful dish requires only a minimal amount of preparation. Don't limit this egg dish to breakfast, it also makes a delicious light lunch or dinner.—Laura Stoltzfus, Leola, Pennsylvania
In a small skillet, brown sausages; drain. In a small bowl, beat egg, milk, salt, pepper and mustard; set aside. Cube bread; place in a greased 8-oz. custard cup. Top with sausage and onion. Pour egg mixture over top. Sprinkle with cheese.
Bake, uncovered, at 350° for 25-30 minutes or until a knife inserted in the center comes out clean.
