Sausage Patties
  - Mix Sausage Patty ingredients in a bowl - use your hands to mix it real good!
  - Shape into 8 patties (thick ones, or 10 Maccers size patties). Make them slightly larger than the muffins because they will shrink when cooking.
  - Heat oil in a large non stick skillet over high heat. Add patties (in batches if needed). Cook the first side for 2 - 3 minutes or until browned. Flip then cook the other side until browned. (Optional: After flipping, top with cheese, cover with lid to melt).


Egg
  - Meanwhile, heat another pan over medium high heat with 1 tbsp oil. Spray egg rings with oil and place in the skillet.
  - Crack egg into the rings. Add around 2 tbsp water into the skillet then cover with a lid. 
  - Cook for 1 - 2 minutes or until egg is cooked to your liking (I like runny yolks).
