These sandwiches are a perfect freezer lunch, snack or dinner. I just microwave them for about a minute and if I'm able I toast it to crisp up the outside. Home made goodness with freezer aisle convenience.
Prep: Start some pulled pork cooking in the crock pot with some water and diced onion, for flavoring I put some fennel, rosemary chili flakes, and large ground pepper in a tea ball.) Make up some dough (pizza, zwieback whatever your fancy) and let it rise, then cook some black beans with all the seasoning you would put in taco meat. Onion, pepper, cumin, garlic, chili powder, etc. mine were not getting soft so per the bean council I added just a bit of baking soda. That did the trick. Then mash them a bit so they're kind of spreadable.
Fold the dough over the filling.
Press the top edges into the bottom half of the dough.
Then roll the bottom half of the dough up over the top edge.
