Place the cottage cheese into a small food processor or high-speed blender. Pulse for 30 to 60 seconds until the texture is completely smooth and airy. If you prefer the traditional texture, you can skip this step, but whipping it creates a more luxurious mouthfeel. Transfer the whipped cheese into a shallow serving bowl and spread it out evenly with the back of a spoon.

Heat the olive oil in a non-stick skillet over medium-high heat. Add the sliced chicken sausage and cook for 3 to 4 minutes until the edges are golden brown and crispy. Toss in the cherry tomatoes and spinach. Sauté for another 2 minutes until the spinach is wilted and the tomatoes are just beginning to soften. Season the mixture with a pinch of salt and pepper if desired.

Carefully pour the hot sausage and vegetable mixture directly over the center of the whipped cottage cheese. The warmth from the toppings will slightly soften the cheese base. Sprinkle the everything bagel seasoning, fresh chives, and red pepper flakes over the top. Serve immediately while the toppings are warm and the base is cool for a delicious temperature contrast.
