Preheat oven to 375 degrees.
On the stove top, heat the olive oil in a skillet over medium heat.
Add in the shallots and cook until tender and translucent.
Add in the spinach and use a rubber spatula or spoon to stir slowly allowing the spinach to wilt.
Remove from heat and allow the spinach to cool.
In a medium mixing bowl, whisk the eggs, milk, salt and pepper.
Add the cooled spinach to the egg mixture and stir.
Pour the liquid into the pie crust.
Add the crumbled goat cheese to the liquid spacing it evenly as possible.
Cook for 35-45 minutes or until the liquid has set and the top of the quiche is just starting to brown.
Cool for 10 minutes. Slice and serve.
