Before starting, preheat the broiler to high. Wash and dry all produce. Core, then cut pepper into 1/4-inch slices. Cut tomato into 1/4-inch pieces.

Heat a large non-stick pan over medium-high heat. When hot, add 1/2 tbsp oil (dbl for 4 ppl), then sausage, peppers, garlic salt and half the Italian Seasoning (use all for 4 ppl). Cook, stirring and breaking up sausage into smaller pieces, until peppers are tender and sausage is cooked through, 6-8 min.** Carefully drain and discard excess fat. Season with pepper, to taste.

Meanwhile, arrange flatbreads on a foil-lined baking sheet. Brush with 1/2 tbsp oil. (NOTE: For 4 ppl, use 2 baking sheets, with 1/2 tbsp oil per sheet.) Broil flatbreads in the bottom of the oven until softened, 1-2 min. (NOTE: For 4 ppl, broil one sheet at a time.) (TIP: Keep an eye on flatbreads so they don't burn!)

Evenly spread marinara sauce across flatbreads. Top with sausage and pepper mixture, then mozzarella and half the Parmesan. Broil in the middle of the oven until cheese melts, 2-3 min. (NOTE: For 4 ppl, broil one sheet at a time.) (TIP: Keep an eye on flatbread pizzas so they don't burn!)

Meanwhile, whisk together vinegar, 1/4 tsp sugar and 1 tbsp oil (dbl both for 4 ppl) in a large bowl. Season with salt and pepper. Add spring mix, tomatoes and remaining Parmesan. Toss to combine.

Cut flatbread pizzas into quarters. Divide flatbread pizzas and salad between plates. Sprinkle chili flakes over top, if desired.
