01 - Preheat oven to 375°F. Grease a Bundt pan thoroughly with nonstick cooking spray.
02 - Heat a skillet over medium heat. Add ground beef and cook, breaking apart with a spoon, until browned, approximately 5–7 minutes. Drain excess fat from the pan.
03 - Sprinkle taco seasoning over the cooked beef. Pour in water and stir until seasoning is evenly distributed. Simmer for 2–3 minutes until sauce thickens. Fold in drained black beans and remove from heat.
04 - Spread one-third of the tortilla chips evenly across the bottom of the prepared Bundt pan. Distribute one-third of the beef-bean mixture over the chips. Sprinkle with one-third of the Cheddar and one-third of the Monterey Jack cheese.
05 - Repeat the layering process two more times: chips, followed by beef mixture, then both cheeses. Finish with the final cheese layer on top.
06 - Place Bundt pan in the center of the oven. Bake for 15–18 minutes until cheese is completely melted and bubbly.
07 - Remove pan from oven using oven mitts. Allow to cool for 3–5 minutes. Carefully invert the pan onto a large serving platter to release the nacho ring.
08 - Scatter diced tomatoes, black olives, green onions, jalapeño slices, and fresh cilantro over the top. Add dollops of sour cream and salsa. Finish with diced avocado.
09 - Serve while hot and crispy. Provide additional salsa and sour cream on the side if desired.
