In a medium baking dish layer half of the zucchini – single layer, touching but not overlapping.
Spread the fried onions over the zucchini
Lay the sliced goat cheese on the onions, also single layer.
Top with another layer of zucchini.
Combine the bread crumbs and paprika, Sprinkle over the top.
Drizzle the melted butter over all, cover and bake for 20 minutes, 400F (200C).
Uncover and bake 10 minutes longer.
Keeping each layer flat allows this to bake in 30 minutes. To increase recipe, either use a larger baking dish, or make a deeper Crumble, adjusting baking time accordingly (with 2 layers of everything I would increase covered baking time by 10 minutes.)
