Line a large sheet pan with parchment paper or aluminum foil. Place a layer of tortilla chips evenly on the pan to cover the bottom. Add pulled pork BBQ evenly over the tortilla chips, and then sprinkle diced onion, black beans over top. Drizzle about 2 tbsp of BBQ sauce over top, and then sprinkle shredded cheese in an even layer. Bake for about 10 minutes, or until the cheese is melted.
While nachos are in the oven, prep the rest of your ingredients: slice jalapeño, chop avocado, and dice green onions. Once nachos are done, drizzle remaining 2 tbsp BBQ sauce over top and Spicy Red Sandwich Spread® to taste. Scatter jalapeño, avocado, and green onions. Serve while warm.
