Sure! Make the filling and just keep it in the fridge for a couple of days. When you're ready to eat the tacos, spread that filling into the tortillas and fry them up! Easy. OR, alternatively, you can freeze these little cuties! Spread the black bean filling into the tacos, fold them, and then freeze them BEFORE frying. When you're ready to eat them, bring to room temp (15-30 seconds in the microwave will do it) and pop 'em back in your skillet till hot, golden, and crispy!
