Preheat your oven to 425°F (220°C) and line a large baking sheet or pizza pan with parchment paper. This helps the flatbread bake evenly and makes cleanup much easier.
Place the cottage cheese into a large mixing bowl. Add the ranch seasoning, garlic powder, smoked paprika, and black pepper, then stir until everything is evenly combined. If you prefer a smoother texture, blend the cottage cheese before mixing in the seasonings.
Fold the cooked shredded or diced chicken into the seasoned cottage cheese mixture until every piece of chicken is evenly coated.
Place the whole wheat flatbreads on the prepared baking sheet and lightly brush the edges with olive oil to encourage a golden, crispy crust.
Spread the chicken and cottage cheese mixture evenly over each flatbread, leaving about a ½-inch border around the edges so the crust can crisp properly during baking.
Sprinkle the shredded mozzarella evenly across the top, then add the diced cherry tomatoes, sliced green onions, and diced red bell pepper, distributing them evenly for balanced flavor in every bite.
Bake for 12–15 minutes, or until the cheese is completely melted, the vegetables are slightly softened, and the edges of the flatbread are crisp and golden brown. For extra browning, switch the oven to broil for the final 1–2 minutes while watching carefully.
Remove the flatbread from the oven and let it rest for 3–5 minutes. This allows the cheese to set slightly and makes slicing much easier.
Sprinkle the chopped fresh parsley over the top and finish with optional toppings such as crushed red pepper flakes, ranch drizzle made with Greek yogurt, fresh basil, or everything bagel seasoning.
Slice into wedges or squares using a pizza cutter or sharp knife and serve immediately while the crust is crisp and the cheese is warm and gooey.
