2. In another bowl, whisk together the soy sauce, sugar, jalapenos and the remaining 4 tablespoons lime juice. Stir in the chopped herbs. Add the portobellos and half the sesame seeds and gently mix until well coated with the marinade. Let stand until softened, about 6 minutes, tossing occasionally to better incorporate the marinade.
3. Transfer half the onions to the bowl with the mushrooms. Toss the spinach in the large bowl with the remaining onions. Transfer to a platter, top with the marinated mushrooms, the remaining sesame seeds and pickled onions. Drizzle with the mushroom marinade and serve.
