In a hot pan with oil, sauté the spaghetti for 2-3 minutes over medium heat. Set aside a small portion of the spaghetti strands to wrap the sausages.
Mix the remaining spaghetti with the tomato purée, season generously with onion powder, paprika, salt, and pepper. Keep warm and let simmer for 10 minutes.
Brown the sausages in a pan over medium heat.
With the reserved spaghetti, wrap each sausage to create a mummy effect, leaving a gap for the eyes. Place the black olive slices in the gap.
Return the sausage mummies to the pan and heat for 5 minutes.
Serve the sauced spaghetti on a plate and top with the sausage mummies.
