Preheat your oven to 350° F. Spray a 9-inch quiche or pie dish with nonstick spray.
Cook the sausage in a large skillet over medium heat, breaking up until cooked, about 5 minutes.
Add zucchini, red pepper, and onion and continue to cook until vegetables are soft. Add garlic and kale and stir for one minute. Sprinkle with pepper and Italian seasoning.
Spread the sausage and vegetable mixture evenly in the prepared dish and top cheddar and parmesan cheese.
Whisk together the milk, half and half, eggs and salt.
Pour the milk and egg mixture in the pan. Bake 35 to 40 minutes, until the center is set and the quiche is lightly browned.
