In a medium-sized saucepan, saute the onion until it softens (add a splash of water or broth if it begins to stick). Add the garlic and ginger root and cook for another minute.
Add the chopped jackfruit, vegetable broth, soy sauce, and hoisin sauce to the pan. Bring to a simmer, cover, and cook on low until jackfruit softens and begins to shred when you press on it with the edge of a spoon (about 20-30 minutes).
Gently “encourage” the larger pieces to fall apart. Then add the remaining ingredients (except lettuce), cover, and simmer until the mushrooms exude their juices, about 5 minutes.
Serve in lettuce cups with sriracha or extra hoisin sauce. May be eaten warm or cold.
On Weight Watchers’ Freestyle program, one serving is 1 point (from the hoisin sauce) with or without the sesame oil, as long as your broth is fat-free.
