Cook the beef. Preheat a thick-bottomed skillet over medium heat. Add the ground beef and break it down with a wooden spoon, cooking until it browns. Add the onion and let it sweat out a bit. Add the roasted cumin, coriander, onion powder, garlic powder, smoked paprika, salt and white pepper, and cook until slightly browned. Pour in the tomato sauce, cover, and let it cook down well. Add the water, cover again, cook a few more minutes, then stir and turn off the heat.
Preheat the oven. Set it to 350F and line a large baking sheet with parchment paper.
Layer. Spread the tortilla chips in a single layer. Drizzle on nacho cheese, then add shredded cheddar and Monterey Jack. Scatter over the drained black beans, then the ground beef. Finish with more shredded cheddar, another drizzle of nacho cheese, and a few more black beans.
Bake. Bake for 10 to 15 minutes, until the cheese has melted through.
Top and serve. Add the diced tomatoes, tomatillo salsa, mild salsa, pickled jalapenos, sour cream and fresh cilantro leaves. Serve immediately.
