Preheat oven to 375ºF.
In a large sauté pan, heat a drizzle of EVOO over medium-high heat. Add beef and brown; season with salt and pepper. Turn heat to medium low and stir in chipotles.
Warm chips slightly in oven on baking sheets. Top with the ground beef mixture, black beans, salsa, jalapeños and cheese. Place back in oven for 5-10 minutes to melt cheese.
To finish, drizzle nachos with crema and diced avocados.
