Drain the water chestnuts and add them to the food processor and hit pulse a few times until they’re all chopped into tiny pieces. and place them into the slow cooker.
Mix together sesame oil, mirin, Bragg's Liquid Aminos, grated ginger, minced garlic, and sriracha if desired, then pour it over the tofu and veggies. Stir to coat the veggies and tofu with the sauce.
Cover with the lid, and set your slow cooker to high for 2 hours or low for 4 hours.
After your filling is done cooking, turn off the slow cooker, take off the lid, and allow it to cool for about 15 minutes before topping with fresh herbs and serving on your choice of romaine or bib lettuce (butter lettuce).
Notes
Use a food processor to quickly chop the veggies into very small pieces.
If using zucchini, only add a small amount (about 1/2 cup) or your mixture will be too wet.
If you want wraps to be spicy, add 1 tsp of sriracha or Chili Garlic Sauce to the dressing.
