Thinly slice the tomato, red onion, and jalapeño pepper. Peel and slice the avocado, then drizzle with lime juice to prevent browning.
In a bowl, combine the ground beef with taco seasoning, chili powder, salt, and pepper. Form into two equal-sized patties.
Heat a skillet or grill pan over medium-high heat. Add a little olive oil and cook the patties for about 3-4 minutes per side, until nicely browned.
During the last minute of cooking, place a slice of cheddar cheese on each patty to melt.
Halve the hamburger buns and toast the cut sides in a dry skillet or on the grill for about 1 minute, until lightly golden.
Spread sour cream on the bottom bun, then top with iceberg lettuce and the cooked patty.
Add the tomato slices, red onion, black beans, and jalapeño pepper.
Top with avocado slices, sprinkle with fresh cilantro, and cover with the top bun.
Serve immediately for the best flavor and texture.
