Heat oven to 400°F.
Place flatbreads on sheet pans. Lightly brush or spray with olive oil. Sprinkle lightly with kosher salt and freshly cracked black pepper.
Bake for 3–5 minutes to lightly crisp. Remove from oven.
In a blender or food processor, combine 2 cups 2% cottage cheese, 2 large cloves of garlic, ¾ teaspoon kosher salt, and several cracks of black pepper. Blend until completely smooth and creamy. Taste and adjust salt if needed.
Spread a generous layer of the blended cottage cheese evenly over each toasted flatbread.
Sprinkle a light layer of mozzarella over the cottage cheese.
Top with spinach, artichokes, and shredded chicken, distributing evenly.
Dollop small spoonfuls of the remaining cottage cheese mixture over the top, similar to a white pizza.
Finish with the remaining mozzarella and sprinkle with Parmesan.
Bake for 15 minutes, until the cheese is melted and the edges are crisp. Broil briefly if desired.
Finish with red chili flakes and a light drizzle of balsamic glaze if using. Slice and serve.
