Notes
Make sure to read the ingredient label on gochujang paste if gluten free, a lot of supermarkets don't stock a gf version. Serpio brand is gf and can be found online/AmazonStorage: Can be eaten hot or cold. If making in advance, prep everything ready but leave assembling last minute so the taco's don't go soggy.
