In a large skillet, brown the sausage until cooked through, about 10 minutes.
In a medium bowl, mix together cooked sausage, mashed potatoes and parsley until well combined.
In a small shallow bowl, beat the eggs.
In another shallow dish, put the flour.
Using a large cookie scoop (I use this one), form the sausage mixture into patties.
Roll the patties in flour, shake the excess, and then dip in the beaten egg. Arrange the patties on a baking sheet.
Heat half of the vegetable oil in a large skillet over medium high heat.
And fry the patties until eggs are cooked, 1-2 minutes per side. Remove the cooked croquettes onto a wire rack lined with paper towel. Continue with remaining oil and patties.
Serve warm for breakfast, brunch, or dinner.
Notes
Note 1: You can substitute ground beef with 1 tablespoon Italian seasoning and 1 teaspoon salt.
