  • 1 large zucchini, sliced very thin
  • 1 small yellow onion, sliced very thin
  • 1 ½ tsp olive oil
  • 2 medium vine tomatoes, sliced thin
  • 1 Tbsp fresh parsley, chopped
  • 5 fresh basil leaves, chopped
  • 1/4 tsp Kosher salt

Preheat oven to 350°.

Toss zucchini, onions, and olive oil in a large bowl. Add parsley, basil, salt, and pepper, and combine well.

Spray an oven-safe dish with olive oil cooking spray.

Create a pattern of alternating 3-4 zucchini slices with onion mixture and a slice of tomato until all the vegetables are in the dish.
