Combine half the chickpeas and all the garlic, almond milk, Worcestershire sauce, olive oil, and soy sauce in a bowl. Mash until as smooth as you can get it.
Add the onions, celery, bell peppers, and remaining chickpeas then stir into the smooth mixture until well distributed. The finer the vegetables are diced the better the outcome.
Add the herb rub, ground flax seeds, and breadcrumbs. Combine until all the ingredients are evenly distributed. As vegetables can change in size and moisture content, add extra breadcrumbs if the mixture is too wet, or more almond milk if the mixture is too dry.
Place the chickpea mixture into a lined pan, or directly into a lined Dutch oven. It is easier cooked in a thin slice, rather than a traditional loaf, which needs more time in the heat.
Bring the Dutch oven to 375 degrees F (190 degrees C) and bake for 30 minutes. If using a pan, place it in a preheated camp oven of the same temperature and cook for the same amount of time.
BBQ Glaze
Combine the BBQ sauce and apple juice to get a glaze-like consistency.
Evenly coat the loaf with the glaze then return to the oven and bake for an additional 30 minutes. Let rest for 10 minutes before slicing and serving.
Alternate Method
If you are in an RV or make the loaf before leaving you may have access to a food processor. This can be used in step 1 to create the smooth mixture, and pulse in step 2 to get the chunky mixture.
