In a large frying pan sauté onions in oil until soft over med/high heat, about 3-4 mins. Add in garlic and continue sautéing for an additional min or until garlic become fragrant. Working in batches add 3-4 handfuls of spinach at a time and cook until wilted. Take off heat. Place a fine mesh colander over a large bowl. Add spinach to colander and using the back of a spoon press against spinach to remove excess moisture. Spinach will release approximately 3/4 cup of moisture.
Preheat oven to 350℉ and grease a 9 1/2 inch pie pan.
Crack eggs into a large mixing bowl and beat. Whisk into egg mixture half and half, dill, salt and pepper. Stir in feta crumbles and spinach mixture. Pour into prepared pie pan and bake for 50-65 mins or until center of quiche is no longer jiggly and an inserted knife comes out clean.
Serve either warm or chilled.
