Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Slice the bell peppers into wide, chip-like wedges, removing all seeds and stems.
Arrange the pepper wedges in a single layer on the prepared baking sheet.
In a small bowl, season the shredded pork with smoked paprika, garlic powder, sea salt, and black pepper.
Evenly distribute the seasoned pork and rinsed black beans over the bell pepper wedges.
Sprinkle the shredded sharp cheddar cheese across the top of the nachos.
Bake for 8 to 10 minutes until the peppers are slightly tender and the cheese is melted and bubbly.
While the nachos bake, mash the avocado with lime juice in a small bowl until creamy.
Remove the pan from the oven and top with the zesty avocado mash, finely diced red onion, and fresh cilantro before serving.
