• Adjust rack to top position (top and middle positions for 4 servings) and preheat oven to 450 degrees. Wash and dry produce. • Halve, peel, and cut onion into 1/2-inch-thick wedges. Slice top off green pepper; core and deseed, then cut crosswise into 1/2-inch-thick rings.

• Place flatbreads on a lightly oiled baking sheet; toast on top rack until golden, 5-7 minutes. (For 4 servings, divide between 2 sheets; toast on top and middle racks.)

• While flatbreads toast, heat a drizzle of oil in a large pan over medium-high heat. Add onion, green pepper, salt, and pepper. Cook, stirring occasionally, until browned and softened, 6-8 minutes. Turn off heat; transfer veggies to a plate. Wipe out pan. • Heat a drizzle of oil in same pan over medium-high heat. Add sausage; cook, breaking meat up into pieces, until browned and cooked through, 4-6 minutes. Pat chicken dry with paper towels and season with salt and pepper. Cook through this step as instructed, swapping in chicken (no need to break up into pieces!) or chicken sausage for pork sausage.

• Meanwhile, in a medium microwave-safe bowl, combine 1/4 cup water and 2 TBSP butter (1⁄3 cup water and 3 TBSP butter for 4 servings). Microwave until water is hot and butter has melted, 1 minute. • Whisk in tomato paste until smooth. Season with salt and pepper.

• Once flatbreads are toasted, remove sheet from oven. Evenly spread flatbreads with sauce, then top with mozzarella, Monterey Jack, sausage, and veggies. Season with salt and pepper. • Bake until cheese melts and flatbreads are golden brown, 3-5 minutes. Top flatbreads with chicken or chicken sausage along with cheese and veggies.

• Allow flatbreads to cool slightly, then slice into pieces. • Divide between plates and serve. Chicken is fully cooked when internal temperature reaches 165°.
