Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch casserole dish.
In a large skillet, heat the olive oil over medium heat. Add the diced onions and cook until softened, about 3-4 minutes.
Add the minced garlic to the skillet and cook for 1 additional minute, stirring to prevent burning.
Stir in the crumbled vegetarian sausage and cook for 4-5 minutes, until heated through and slightly browned.
Add the fresh spinach to the skillet, a handful at a time, and cook until wilted. Remove the skillet from the heat and set aside.
In a large mixing bowl, whisk together the eggs, milk, salt, pepper, and red pepper flakes (if using).
Stir in the shredded cheddar cheese, grated parmesan cheese, and cubed bread, ensuring that the bread is evenly coated with the mixture.
Fold the sausage-spinach mixture into the bread mixture until everything is evenly combined.
Transfer the mixture into the prepared casserole dish, spreading it out evenly.
Bake the casserole in the preheated oven for 40-45 minutes, or until the top is golden brown and the casserole is set in the center.
Remove the casserole from the oven and let it rest for 5-10 minutes before slicing and serving.
