Preheat broiler.
Heat olive oil in a large skillet over medium-high heat. Once the oil is hot, add in the turkey and cook, breaking it up into small pieces with a wooden spoon or a potato masher.
Once the meat is just about cooked through, add garlic, chili powder, cumin, smoked paprika, oregano, salt and pepper. Deglaze the pan with a few tablespoons of stock or water, and remove from heat.
While the turkey is cooking, arrange tortilla chips in an even layer on a large sheet tray. Top with turkey mixture and scatter black beans over the top. Top with cheddar cheese and broil in the oven for about 2-3 minutes, or until the cheese has melted.
Top hot nachos with avocado, romaine, yogurt, red onion, cilantro, lime juice and jalapeños.
