Preheat oven to 425 degrees and line a baking sheet with parchment paper.
Spread potatoes out on the baking sheet and top with 1 tablespoon of olive oil and 1/2 of the packet of taco seasoning. Toss to coat evenly. Place in the oven for 15 minutes.
While the potatoes are roasting, prepare the chipotle cilantro sauce. Add all of the ingredients to a blender or food processor and pulse until combined.* Taste and adjust seasonings as needed. Set aside.
Remove the potatoes from the oven and add the bell peppers, onions, soyrizo, remaining taco seasoning and remaining tablespoon of olive oil to the baking sheet. Toss to combine and place back in the oven for 15 minutes.
To assemble, add a layer of chips to the bottom of a cast iron skillet (or baking dish) and top with 1/3 of the potato/soyrizo mixture, followed by half of the black beans and a drizzle of the chipotle sauce. Repeat this layer. Finally, add a layer of chips and the final 1/3 of potato/soyrizo mixture.**
Place the nachos in the oven under the broiler for 3-5 minutes, or until warmed through.
Remove from the oven and top with additional chipotle cilantro sauce, cilantro, avocado and jalapeño. Serve with lime wedges.
