Preheat your oven to 375°F (190°C).
Grate the carrots, potatoes, and zucchini. Squeeze out excess moisture from the zucchini using a clean kitchen towel or cheesecloth.
Finely chop the onions and mince the garlic.
In a large bowl, combine the grated vegetables, chopped onions, and minced garlic.
Add the flaxseed or chia seed mixture (or plant-based yogurt) to the vegetables.
Add vegetable oil, salt, pepper, and your chosen fresh herbs. Mix well.
If using whole-grain bread, blend the slices into crumbs using a food processor.
Mix the breadcrumbs into the vegetable mixture.
Grease a baking dish with a bit of oil.
Spread the vegetable mixture evenly in the dish.
Bake in the preheated oven for about 45-50 minutes, or until the top is golden brown and the bake is firm to the touch.
Let the bake cool slightly before slicing and serving.
