First, you want to marinate the soy curls. After soaking them according to the package directions, drain them and squeeze any excess water out of them. Set aside.
In a large mixing bowl, combine the lime juice, soy sauce, rice wine vinegar, vegetable oil, brown sugar, garlic and shallot. Whisk to combine.
Now, you want pound the stalks of lemongrass and either very finely mince the lemongrass, or put it in a food processor and pulse to puree it, it is hard to eat large chunks of lemongrass, it is tough and fibrous. I enjoy larger chunks, but that is definitely not for everyone. You may also find already pureed lemongrass paste, that is pretty common and easy to use!
Add the lemongrass, and vegetable broth to the bowl now, and whisk again to combine everything.
Pour the soy curls into the bowl with the marinade. Toss to combine and press the soy curls down in the marinade as much as possible. Let the soy curls marinate for at least 1 hour, tossing a few times to make sure the soy curls are evenly marinated.
While the soy curls marinate, make the peanut sauce. Whisk all the peanut sauce ingredients together starting with 2 tablespoons of warm water, then add more warm water as needed to smooth and thin out the sauce to your preference. Set aside.
Once you are ready to make the soy curls, remove them from the marinade, but reserve the marinade.
Heat the olive oil on medium high in a large non-stick or cast iron skillet.
Add the soy curls and sauté, reducing heat as needed, until the soy curls are nice and brown and have a little char on them. About 10 to 12 minutes.
While the soy curls sauté, whisk the cornstarch into the reserved marinade.
Once the soy curls are brown and a little crisp on the outside, pour the marinade into the skillet with the soy curls and stir to combine. Let the soy curls simmer in the marinade for a few minutes, the marinade will thicken up and turn into a nice sauce.
Taste and adjust seasonings.
When the soy curls are done, serve them over steamed rice, drizzled with some peanut sauce, topped with cilantro and extra chili crisp or chili sauce if desired.
