Spicy Asian Dressing for Thai Chicken and Noodle Salad

I've made this recipe without using the fish paste and it tastes great without it.... actually to the point that I wouldn't even bother adding it. But yes, you could use fish sauce (which is what you'd add to a Vietnamese Bún chả dish).

what can i use for a husband that's deathly allergic to all fish? :(

Fish sauce would be a good substitute.

What can I use as a substitute to the anchovy paste?
