Preheat your oven to 400°F (200°C).
In a skillet, cook the ground beef or chicken until browned; drain excess fat.
Add black beans and salsa to the meat; stir to combine.
Line a large sheet pan with tortilla chips.
Spread the meat and bean mixture evenly over the chips.
Sprinkle shredded cheddar cheese generously across the top.
Add sliced jalapeños for an extra kick.
Bake in the preheated oven for 15 minutes or until the cheese is bubbly.
Remove from the oven and top with diced tomatoes and chopped green onions.
Serve immediately with sour cream and guacamole on the side.
