Having someone else cook for you can be a real treat especially when you are low on funds or ideas. Maybe your roommate wanted to be creative. Individually spaghetti or palm oil are not strange ingredients. I guess together the dish was strange indeed as it made you sick. Is that all that was in the dish or could there have been another ingredient that made you ill.
Sphaghetti is an easy to make dish even without fancy sauces - how did your roommate get it wrong? I am sure you must have thought so. Well you certainly learnt a lesson. I hope you were not sick for too long.
