Breakfast sausage is very simple – pork, salt, and spices.  Here is a link to a version with just 3 ingredients:  Simple American Breakfast Sausage . 

This posting is an adaptation of a recipe in livingthegourmet.com, which involves more ingredients, but is still very simple.  It makes just over a pound of sausage.  I made the sausage just before cooking it (and it was fine) but it is better to mix the pork and spices the night before to give the flavors time to meld.

1 lb. ground pork

1 Tbs. dark brown sugar

1 large clove garlic, finely chopped

1 tsp. salt

1 tsp. freshly ground black pepper

½ tsp. fennel seeds

1 tsp. dried oregano

½ tsp. dried rosemary

½ tsp. dried sage

Grind the herbs together in a mortar and pestle.  Mix in the sugar, garlic, salt, and pepper.  Then in a medium bowl mix together the herb mixture with the pork until all the flavorings are evenly mixed.  If time permits, let the sausage meat rest in the refrigerator overnight before forming into patties. 

Depending on how fatty the pork is, you may need some oil in the pan to fry them.
