First prep the marinade. Toss everything into a small food processor (Magic Bullet works perfect) and puree until relatively smooth.
Remove mock duck from the cans and give em a little squeeze over the sink to drain some of the moisture. Place in a bowl and smother in the marinade. Let marinate for about an hour, turning a couple of times to keep everything evenly coated.
Now prepare the broth.
Preheat a stock pot over medium heat. Dry toast the coriander seeds for about 3 minutes, until they’re fragrant and a few shades darker. Add the onion, garlic and ginger and saute for about 15 minutes. Add the lemongrass, salt, broth and water. Cover and bring to a boil. Once boiling, lower to a simmer for about 30 more minutes, or until everything else is done. When done, strain in a fine mesh strainer (remember to have a large bowl underneath obviously) and return to the pot to keep warm. Squeeze in the juice of a lime.
Now prepare your noodles according to package directions. Once they are ready, drain and rinse under cold water and set aside. It’s okay if they’re at room temp.
In the meantime, this is a good time to prep all your veggies and accoutrement.
Now prepare the mock duck.
Preheat a large pan (preferably cast iron) over medium heat. Drizzle a little peanut oil in the pan. Saute mock duck for about 10 minutes, until nicely browned. Oh, and if you like things spicy, add a big pinch red pepper flakes while sauteing.
