1. Heat a saute pan over medium heat with oil. Saute onions and garlic for 2 minutes. Add sweet potatoes. Season this mix liberally with the Cajun seasoning and pepper.
2. Let this mix cook for 15 minutes or so until the potatoes are soft. You may want to add a 1/2 cup water and cover pan to speed this process along.
3. When potatoes are soft, add the black beans and the zest of 1 lime. You may also want to add more Cajun seasoning to help further flavor the beans. Cook until the beans are heated through and you think the flavors have melded. Right before serving, squeeze some lime juice over the dish.
Serve over a bed of brown rice or, if you feel like some creative nachos, you can serve this on a bed of whole grain tortilla chips then melt vegan mozzarella or cheddar "cheese" over the top. ( I like Follow Your Heart "cheese" the best.) It melts fabulously.
