In a medium bowl, combine warm ground beef, salsa, and taco seasoning until well combined. Then add black beans, onion powder, salt and pepper. Mix well.*

To prepare the avocados, scoop out a small amount of avocado from each avocado shell with a spoon and squeeze a small amount of lime juice over each to prevent the avocado from browning quickly. Make sure the lime juice covers the green portion of each avocado.

Fill each avocado with enough taco filling to almost overflow.

Top each with lettuce, grape tomatoes, and cheese. Add any preferred toppings.

Serve while ground beef is still warm with lime wedges for added flavor.
