FOR THE SWEET POTATOES: Preheat the oven to 450 degrees and line a baking sheet with foil. Add potatoes, olive oil, paprika, cumin and lime juice to a bowl. Stir to combine. Spray foil with non-stick spray. Add potatoes to the baking sheet and bake for 30 minutes, flipping halfway through. Remove from the oven and add salt.
FOR THE COLESLAW: While the potatoes are cooking, add the coleslaw ingredients to a bowl and stir to combine. Refrigerate until ready to use.
FOR THE BEANS: Add beans, cumin and red pepper flakes to a pan. Heat on low while potatoes are cooking, stirring frequently.
TO ASSEMBLE TACOS: Heat tortillas in a non-stick pan or over direct heat. Add beans, sweet potatoes and coleslaw to each taco and eat as is or add optional toppings.
