In a small bowl, whisk together eggs, milk, and salt and pepper.
In a separate bowl, combine the remaining ingredients. Pour the whisked egg mixture into the corn and zucchini mixture and stir to combine.
Using an immersion blender, process the quiche mixture until mist of the corn kernels are broken down, but leaving some whole. Pour into prepared dish.
Place in oven and bake for 35-40 minutes or until a knife inserted near the center comes out clean. Let stand for 10 minutes before serving. Cut into 6 slices.
