Pad Thai- Sesame oil or fish oil?

So, I do know that thai food is filled with taste most importantly fish oil is the common ingredient in their food although you don't taste it as strong as you would if you were eating actual fish....
So, I am at a process of making my own version of Pad Thai: Peanut Satay sauce, rice noodles, veggies, tofu, shrimp and chicken...however, I am not sure if I can make it authentic since I am skeptical to use fish oil....so, should i reconsider and use sesame oil? Would that go well with 3 meats: TOFU (Vegan), Shrimp and Chicken?

Sage or thyme?

So, i came up with my own creation of butternut squash soup. My mother-in-law insist that sage taste better than thyme to add essence to the soup. I tried thyme, I liked it and sage was good too. Can't really make up my mind....So what do you think? Sage or thyme?
