Mix the cooked spaghetti: In a large bowl, add 14 oz cooked spaghetti, 2 medium eggs, 2 tbsp flour, 1/4 tsp ground black pepper and 1/4 tsp salt. Toss well to coat evenly.

Pan-sear the smoked sausages: In a skillet over medium heat, add 4 oz smoked sausages. Flip to cook for a total of 4 minutes until both sides are slightly browned.
