Prepare the vegetables: Slice the zucchini thinly in rounds and chop the onions. Slice the zucchini flowers, if using.
Optional: let the vegetables rest in the refrigerator for 2 hours to release all of their moisture.
Add the flour, salt, pepper, and oil to vegetables. Mix well until a creamy dough forms. If necessary, add a little water to make it less dry.
Coat a baking pan (35 x 25 cm) with olive oil and pour the mixture, gently pressing it to evenly coat the bottom of the pan to make ~1 cm thick layer.
Bake at 190 °C for 30 minuti, until a nice golden crust forms.
