Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Slice the mini bell peppers in half lengthwise and remove any seeds to create sturdy 'chips'.
In a medium bowl, toss the shredded pork shoulder with the smoked paprika, ground cumin, sea salt, and black pepper until well coated.
Arrange the pepper halves on the prepared baking sheet and fill each one with a generous portion of the seasoned pork.
Roast for 8-10 minutes until the peppers are tender-crisp and the pork is heated through.
While the nachos roast, combine the Greek yogurt, avocado, and lime juice in a small blender or bowl, whisking until the crema is velvety and smooth.
Remove the peppers from the oven, sprinkle evenly with nutritional yeast for a savory cheesy flavor, and drizzle with the avocado crema.
Garnish with fresh cilantro and serve immediately.
