Preheat oven to 375°F (190°C).
In a medium bowl, combine dry soya mince with hot vegetable broth and let sit for 10 minutes to rehydrate.
Finely dice the onion, zucchini, and garlic.
Heat olive oil in a skillet over medium heat and sauté the onion and garlic until translucent.
Add the zucchini to the skillet and cook for 3-4 minutes until slightly softened.
Stir in the rehydrated soya mince, tomato puree, oregano, sea salt, and black pepper.
Transfer the mixture to a small baking dish and spread evenly.
Sprinkle nutritional yeast over the top to create a savory crust.
Bake for 20-25 minutes until the edges are bubbling and the top is lightly browned.
