Preheat oven to 375°F (190°C). Grease a casserole dish like you mean it.
Sauté veggies: Heat oil in a skillet. Cook onion, garlic, bell pepper, mushrooms, and zucchini for 5–7 minutes.
Add jackfruit: Toss in shredded jackfruit, paprika, oregano, salt, and pepper. Stir and cook for another 8 minutes.
Mix the sauce: In a bowl, whisk coconut milk, nutritional yeast, and cornstarch until smooth and delusion-free.
Combine it all: In a large bowl, mix cooked rice, sautéed mixture, and creamy sauce. Stir like your life depends on it.
Transfer and bake: Spread mixture in casserole dish, top with vegan cheese if using, and bake for 30 minutes until bubbly and golden.
Serve hot: Let it rest 5 minutes so no one burns their taste buds off, then serve with sass.
