To make a broccoli stuffed shells cheese recipe, first you need to prepare the filling. First, you'll need the following ingredients: 1 1/2 cups shredded cheddar cheese, 1 cup chopped scallions, 2 tbsp. olive oil, and 1 teaspoon each salt and pepper. Toss the ingredients together until they're evenly coated. Place the cheese mixture in the bottom of an 8x8x2 inch baking dish. Fill each shell with the broccoli mixture. Cover the dish with plastic wrap and refrigerate until ready to use.
