How to take Accutane?

I understand that you should take accutane tablets with the fattiest and Highest calorie meal per day to promote max absorption. I don’t often eat typically high fat foods but I do take an blackmores omega 3 supplement after breakfast each day. I’m wondering whether any breakfast (usually eggs and toast or a fruit smoothie) + the omega 3 supplement will do the same as a ‘fatty meal/food’ in facilitating max absorption? Or should I just try to incorporate a high fat meal once per day instead?
