Zucchini-Tomato Gratin

READY IN: 40mins
Recipe by RedVinoGirl

This is a light, flavorful side dish (or main dish) that is PERFECT for summer! The steps to salt the zucchini and tomatoes isn't mandatory but will prevent this dish from getting soggy because it eliminates all excess moisture during the cooking process. The taste will remain unchanged so it's skippable, if short on time but you may have to pick this up with a slotted spoon if skipping this step.

The combination of tomatoes drained, zucchini cooked well,and parmesan or mozzarella,is absolutely fantastic! My tastebuds would be happy for this to be the whole meal:)
