Preheat your oven to 425°F.
In a bowl, whisk together the chickpea flour, egg white, nutritional yeast, a pinch of salt, and a few cracks of pepper. Add just enough water to form a smooth, spreadable batter.
Spread the batter evenly on a lightly oiled baking sheet or pizza stone to form a thin flatbread.
Place the flatbread in the oven and bake for 10 minutes until set but not browned.
Meanwhile, chop the red bell pepper, zucchini, red onion, and eggplant into bite-sized pieces. Toss them with olive oil, fresh herbs, salt, and pepper.
Spread the vegetable mixture on a baking tray and roast in the oven for 12-15 minutes until tender and slightly caramelized.
Remove the flatbread from the oven and top it with the roasted vegetables.
Crumble the goat cheese evenly over the vegetables.
Return the flatbread to the oven for an additional 3-5 minutes, just until the goat cheese softens slightly.
Slice and serve warm, enjoying the balance of nutty chickpea flatbread, savory roasted vegetables, and creamy goat cheese.
