Adjust rack to top position (top and middle positions for 4 servings) and preheat oven to 450 degrees. Wash and dry produce.

Trim and halve zucchini lengthwise; slice crosswise into ½-inch-thick half-moons. Peel garlic and place in the center of a small piece of foil; drizzle with olive oil and season with salt and pepper. Cinch into a packet. Halve tomatoes. Mince chives.

Toss zucchini on a baking sheet with a drizzle of olive oil, 1 tsp Italian Seasoning (2 tsp for 4 servings), salt, and pepper. Place garlic foil packet on same sheet.

Roast on top rack until zucchini is browned and tender, 12-15 minutes.

Meanwhile, place tomatoes in a medium bowl; toss with a drizzle of olive oil, 1 tsp Italian Seasoning (2 tsp for 4 servings), salt, and pepper. (You’ll use the rest of the Italian Seasoning later.) Set aside to marinate.

Once zucchini is tender, transfer to bowl with tomatoes; toss to combine.

Leaving garlic foil packet on sheet, carefully wipe off any excess oil. Place flatbreads on same sheet. (Divide between 2 sheets for 4 servings.)

Return to top rack until flatbreads are lightly toasted and garlic is softened, 5-7 minutes. (For 4, toast on top and middle racks; swap rack positions halfway through toasting.)

While flatbreads toast, melt 1 TBSP butter (2 TBSP for 4 servings) in a large pan over medium-high heat. Add flour, garlic powder, and remaining Italian Seasoning. Whisk constantly until lightly browned, 30 seconds.

Reduce heat to medium low and whisk in cream cheese and ½ cup water (1 cup for 4) until melted and combined. Season generously with salt and pepper. Simmer until thickened, 1-2 minutes. Remove pan from heat.

Once garlic is done, carefully transfer to a cutting board and roughly chop.

Heat broiler to high.

Evenly top flatbreads with sauce, roasted garlic, and veggies. Sprinkle with mozzarella.

Broil flatbreads until cheese melts, 1-2 minutes. (For 4 servings, broil in batches.) TIP: Watch carefully to avoid burning.

Slice flatbreads into pieces; sprinkle with chives and chili flakes to taste. Divide between plates and serve.
