Place a lightly oiled baking sheet on top rack (for 4 servings, use 2 lightly oiled baking sheets on top and middle racks) and preheat oven to 450 degrees. Wash and dry produce.

Trim and halve zucchini lengthwise; thinly slice crosswise into half-moons. Halve tomatoes. Peel and mince or grate garlic. Zest and quarter lemon.

Heat a drizzle of olive oil in a large pan over medium-high heat. Add zucchini and cook, stirring, until lightly browned and softened, 5-6 minutes. Season with salt and pepper.

While zucchini cooks, in a small bowl, combine tomatoes, garlic, and a drizzle of olive oil. Season with salt and pepper.

In a second small bowl, combine ricotta, half the lemon zest, ½ tsp olive oil (1 tsp for 4 servings), and lemon juice to taste. Season with salt and pepper.

Carefully place flatbreads on prepared sheet (divide between both prepared sheets for 4 servings). Evenly spread flatbreads with lemon ricotta. Top with zucchini and tomatoes, cut sides up.

Bake on top rack (top and middle racks for 4) until flatbreads are golden brown, 10-12 minutes.

Meanwhile, pick parsley leaves from stems; roughly chop leaves.

Once flatbreads are done, garnish with parsley, remaining lemon zest, and chili flakes to taste. Drizzle with honey, then slice into pieces.

Divide between plates and serve with any remaining lemon wedges on the side.
