Preheat oven to 400℉. Line a 7x11 inch pan with parchment paper.
DO NOT squeeze out any liquids from the veggies.
In a large bowl, combine the potato, zucchini, onion, dill, garlic, eggs, olive oil, almond flour, breadcrumbs, salt, pepper, and water. Mix until incorporated. Fold in the crumbled feta cheese. Transfer the mixture to the prepared pan and spread out evenly. Top with everything bagel seasoning.
Bake for 45-50 minutes or until golden brown on top. Transfer to a wire rack and allow to cool before slicing.
