Battered squash with caramelized onions and black olives~

Angela's recipe: Dredge thin slices of squash in flour, fry in hot olive oil, drain on paper towels. Caramelize thin slices of onion, adding a spoon of sugar and a bit of vinegar near the end, throwing some black olives on top to warm. Place squash slices on a plate, lightly salting each layer, and place the onion mixture on top. Buonissimo!
