(from canned chipotles in adobo sauce)
Preheat the oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Toss the sweet potatoes with a drizzle of olive oil and a pinch of salt and pepper. Spread in a thin layer on the baking sheet and bake for 15 minutes. Top with the cheese and bake for an additional 10 minutes or until the cheese is melted and the sweet potatoes are golden brown.
Remove the baking sheet from the oven and top the sweet potatoes with the black beans, mango, radishes, avocado, and serrano pepper. Add a squeeze of lime, drizzle with the adobo sauce, and sprinkle with a few pinches of salt. Serve straight from the pan with extra lime slices on the side.
