shredded cheese (any kind - melting or hard non-melting, or a combo of both)
How to Make Marinated Spaghetti:
In two separate pots- boil cubed potatoes - cook spaghetti as instructed on packaging - remove both from heat when cooked but still firm. Run under cold water; drain and set aside. Heat olive oil in pan, add chopped onion and garlic ( plus shrimp, if used) and stir for a minute. Remove from heat. Add cooked spaghetti, potatoes , salt, pepper, seasoning, cheese, balsamic vinegar (per taste), olives, and mix well right away.
Leave covered to marinate for an hour. Can be eaten cold or heated up in the microwave.
Tastes even better the next day .
Add in spinach and or tomatoes at the end, if you like, just a few minutes before serving (tastes better that way - fresh and not too cooked).
