1
Heat a large skillet over medium-high heat. Add the ground beef and onion. Cook for 6-8 minutes, breaking up the meat as it cooks. Add the tomato paste and taco seasoning. Stir well. Taste and season as needed. If the meat seems thick at all, add 1-2 tbsp of water.

Slice the avocados in half and remove the pit. If desired, scoop out a little of the avocado to have more room for the filling. You can always pile it on top after.

Stuff the avocados with the ground beef mixture. Then top with all your favorite toppings - shredded lettuce, tomatoes or pico de gallo, shredded cheese, salsa, sour cream, cilantro, crushed-up tortilla chips, etc.
