Divide kale between 2 large baking sheets (amount as original recipe is written // adjust if altering batch size) and spread into an even layer, making sure the pieces aren't overlapping to ensure crispiness. You may need to bake them in 2 batches (or more if increasing batch size) depending on size of baking sheets.
Heat a large skillet over medium heat. Once hot, add 1 Tbsp oil and spread to coat the surface. Then add sliced sweet potatoes in a single layer. Cover to steam.
To serve, arrange kale chips on a serving platter and top with sweet potatoes, black beans, and any other desired toppings, such as avocado, salsa, cilantro, or red onion. Serves 2 as an entrée or 4 as a side (amounts as original recipe is written // adjust if altering batch size).
