1.Preheat oven to 375(F) degrees. In a medium pot, heat oil over medium-high. Add onion and cook until softened, about 6 minutes. Add flour and cook, stirring constantly, 1 minute. Gradually add milk, whisking constantly, and cook until slightly thickened and bubbling, about 3 minutes. Season with salt and pepper and let sauce cool slightly.
2.In a food processor, combine bun, Parmesan, Italian seasoning, and red-pepper flakes. Process until fine crumbs form. Transfer half the mixture to a large bowl and combine with spinach, tuna, and half the sauce; season with salt and pepper. Fill each shell with 2 heaping tablespoons spinach mixture and place in a 9-by-13-inch baking dish. Top with remaining sauce and breadcrumb mixture. Bake until sauce is bubbling and breadcrumbs are golden, about 20 minutes.
To simplify, replace the large shells with small shells and mix them in with the tuna and spinach mixture to make a quicker casserole.
