In a large skillet, brown the ground beef and sprinkle with taco seasoning. Add 1/3 cup water and cook until liquid reduces.
Place avocados on a baking sheet. Scoop 1/4 of the beef mixture into each avocado. Drizzle one tablespoon of enchilada sauce on top of each beef mixture. Top with 2 tablespoons of cheese. Broil for 3-5 minutes or until cheese is melted and avocados are warm.
Top with desired toppings such as sour cream, salsa, or cilantro
