Preheat the oven to 375 degrees. Press the crust into the bottom and up the side of the pan. Use a fork to poke holds into the bottom of the crust.
Bake the crust in the center of the preheated oven until golden brown. If making mini quiches - the crust will only take 2-3 minutes, for a full-size quiche, about 7 minutes. Remove the crust from the oven and reduce the temperature to 350 degrees.
While the crusts are baking, grate the zucchini onto a clean kitchen towel and squeeze dry. Add the oil to a skillet and heat over medium heat until hot. Add in the shallots and cook until nice and soft. Add in the zucchini and turn up the heat to high. Cook the zucchini and shallots for an additional 3-5 minutes.
Combine the flour, baking powder, and salt in a small bowl. In a separate bowl, beat the eggs until nice and fluffy (2-3 minutes). Grate the cheese - I used a sharp cheddar and Dubliner cheese mix for this quiche. I've had it with Monterey Jack, pepper jack, white cheddar - ALL are good so use your favorite combination. Add in the grated cheese, cottage, zucchini mixture, green chiles, and flour mixture and beat until combined.
Pour the mixture into the crust(s). Bake the quiche until the top is puffed and golden brown and a toothpick inserted into the center comes out clean. For the mini quiches, around 25 minutes, for a full-sized quiche, 35 -40 minutes. Let stand for several minutes before removing from pan and serving. Enjoy!
