Instructions:

Add vegetable oil to a large pan and heat over medium-high heat.

Add sausages and cook until browned on all sides.

Remove sausage from pan and set aside (Note: You do not need to cook it through at this point.)

Add onion and peppers to grease left in pan and cook over medium heat until softened.

Add garlic and cook for 1 minute.

Slice sausage into 1 to 1 1/2-inch pieces.

Return sausage to pan along with all other ingredients.

Cook for 5 to 10 minutes, until sausage is cooked through and sauce is thickened.

Serve on hoagie rolls if disered.
