Preheat oven to 375°

Begin heating a large pot of water to boiling. Add pasta shells to boiling water. (add a drizzle of olive oil to prevent pasta from sticking) Cook pasta 2 minutes less than package instructions. Drain and let cool.

Brown ground beef in large skillet. Drain grease and return meat to skillet. Add taco season, water and green chiles. Heat over medium/low until liquid is absorbed.

Fill pasta shells with a large spoonful of meat and a small spoonful of salsa. Pack shells tightly and in an even layer in a 9x13 baking dish. Top each shell with 2-3 sliced olives. Cover shells with shredded cheese. Bake for 10-15 minutes or until heated through and cheese is melted.

Serve with sour cream, salsa, sliced avocado and fresh cilantro.
