let me tell you something, brother. I haven't tried it with fish sauce, but I did whip up a killer tuna wrap with parmesan cheese, garlic, Greek yogurt, Worcestershire sauce, mustard, salt, pepper, and a squeeze of lemon juice. And let me tell you, it was the best dang tuna wrap I've ever had in my life! Loco really knocked it out of the park with this one. I'm thinking of taking it to the next level and adding some more Asian flavors with Worcestershire sauce. Thanks for the tip!
