Preheat oven to 400 f.
Wash, scrub then slice your sweet potatoes into 1/4 inch rounds. (I like to use a mandolin for this)
Place the sweet potato rounds in a large bowl and toss with oil, all seasonings, sea salt and pepper.
Arrange onto two baking sheets so that none are over-lapping, or touching.
Bake for 15 minutes, then flip the rounds on the other side and bake for an additional 6-7 minutes.
Remove sheets from oven and combine sweet potatoes onto one large sheet.
Top with black beans and cheese and place back in the oven for an additional 5 minutes or until the cheese is all melty.
Remove from oven and top with tomato, jalapeƱos and fresh chopped cilantro .
Serve immediately.
