Preheat your oven to 180℃ (360℉) on the fan grill (turbo grill) setting.
Roughly chop all the vegetables into large chunks, then place them in a food processor. Pulse until they are finely chopped into small pieces.
Heat about 2 tablespoons of olive oil in a large skillet over medium heat. Add the chopped vegetables and cook, stirring occasionally to prevent burning, until they soften and reduce slightly.
While the vegetables are cooking, bring a pot of water to a boil and cook the macaroni noodles according to the package instructions.
Add the cooked noodles to the skillet and toss to combine.
In a bowl, whisk the eggs together with the garlic powder, salt, and pepper until well combined.
Add the cottage cheese, most of the grated mozzarella and parmesan (reserving a handful for sprinkling on top), and the whisked eggs to the skillet. Toss everything together until well combined.
Rub about 2 tablespoons of olive oil into your casserole dish, then add the ziti mixture. Sprinkle the reserved grated cheeses on top.
Bake for 20 minutes, or until the top is crispy and golden.
