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 lengthwise. 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, tossing halfway through, until zucchini is browned and tender, 14-16 minutes.

Meanwhile, place tomatoes in a medium bowl; toss with 1 tsp Italian Seasoning (2 tsp for 4 servings), a drizzle of olive oil, 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. (For 4 servings, divide between 2 baking sheets; toast on top and middle racks, swapping rack positions halfway through toasting.)

Return to top rack until flatbreads are lightly toasted and garlic is softened, 5-7 minutes.

Heat a drizzle of oil in a large pan over medium-high heat. Add sausage* and cook, breaking up meat into pieces, until browned and cooked through, 4-6 minutes. Turn off heat; transfer to a plate. Wipe out pan.

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 roasted 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.

Use pan used for sausage here.

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.

Top flatbreads with sausage along with veggies.
