Instructions

• Heat the oven to 375°F. Cook the shells in salted boiling water until just tender, then drain and cool enough to handle.
• Brown the ground beef in a skillet over medium heat, breaking it into small pieces. Drain excess fat if needed, then stir in the taco seasoning and 1/2 cup water. Simmer for 3 minutes.
• Spread 1/2 cup salsa in a 9-by-13-inch baking dish. Fill each shell with the seasoned beef and arrange the shells in the dish.
• Spoon the remaining salsa over the shells and sprinkle with half of the cheddar. Cover with foil and bake for 20 minutes.
• Uncover, add the remaining cheddar, and bake for 5 to 10 minutes more, until the cheese is melted and the filling is hot.
• Rest for 5 minutes. Top with sour cream and green onions before serving.
