Preheat the oven to 400 degrees.

In a medium skillet heat the sausage over medium heat. Cook for 5 minutes, crumbling the sausage as it cooks. Add in the onions and garlic and cook for 5 additional minutes. Remove from heat.

Place the pie crust in a pie pan. Set aside.

In a large bowl beat the eggs and milk together. Add in the kale, red bell pepper, rosemary, and 3/4 c. of cheddar cheese. Mix well.

Add in the sausage mixture and mix until just combined. Pour the mixture into the prepared crust and sprinkle with remaining cheese.

Bake for 40-50 minutes or until the quiche is set in the center and the crust is browned. Remove from oven and cool for 5 minutes before cutting and serving.
