Instructions
Preheat your oven to 375°F (190°C).

Mix in the canned diced tomatoes and vegetable broth. Stir everything together.
Sprinkle the gluten-free flour over the mixture, stirring to combine and thicken slightly. Add the dried basil, dried oregano, salt, and black pepper. Simmer for 5 minutes.
Transfer the vegetable mixture into a 9x13-inch baking dish.
In a small bowl, combine the gluten-free breadcrumbs with the remaining 1 tablespoon of olive oil and grated parmesan cheese. Mix until well combined.
Spread the breadcrumb mixture evenly over the top of the casserole.
