Substitute canned corned beef with lean ground pork, and swap out nutrient-deficient potatoes for beta-carotene and vitamin C-rich sweet potatoes. Flavor with spices found in spicy Italian sausage to create a preservative-free, completely unprocessed breakfast. Added bonus: a runny yolk provides a delicious "sauce" for your hash.
