Rehydrate the soya mince in warm water according to package directions. Add in vegetable broth powder for extra flavor.
Thinly slice the green onions and save the green parts for later. Peel the carrots and core the red pepper. Cut them into long strips and into small dice.
Heat a large skillet with your preferred cooking oil. Add in the white part of the onions, red peppers, and carrots. Cover with a lid and cook over medium heat for 10 minutes, stirring occasionally.
In the meantime, wash the butter lettuce leaves. Dry them with a clean kitchen towel or in a salad spinner.
Drain the soya mince and press out the excess liquid with a spoon. Add it to the vegetables. Sauté over medium-high heat without a lid for 3 minutes.
For the sauce, mix the cornstarch with the rice vinegar (or water). Add in the tamari, sesame oil, minced garlic, and grated ginger.
Add the sauce to the skillet and stir for 1 minute until it thickens.
To serve, spoon the filling into the lettuce leaves and top with the green onions you saved. Serve with rice if eating it as a main dish.

Notes
Use a vegetable chopper to save time chopping the vegetable.
Add shiitake mushrooms and collard greens for a veggie-loaded filling. Let the excess water cook off without a lid before you add in the soya mince.
Note: Asian lettuce wraps often call for hoisin sauce for the filling. As most of the options available at the grocery store are not gluten-free, I consciously didn't add it to this recipe.
Serve the wraps as a main dish with rice on the side on stir rice noodles into the filling at the very end.
