1 package Prepared Pie Crust (bottom Crust Only)
1/2 whole Onion, Sliced And Caramelized
1/2 sticks Butter, Plus 1 Tablespoon, Divided
3 whole Portobello Mushrooms, Sliced (discard Stems)
1 cup Ham, Diced
1- 1/2 cup Swiss Cheese, Grated

1
Prepare the deep dish pie plate with the unbaked crust.
2
Cook sliced onion on medium to medium-high heat in 1/2 stick of butter for about 20-25 minutes until they are a beautiful golden brown.
3
Toss the chopped mushrooms into the same pan as the onions, add a tablespoon of butter and cook for another 5 minutes.
4
Dice the ham (I used leftover ham from Sunday lunch) and grate the cheese while the onions cook.
5
Whisk together the eggs, cream, salt and pepper until frothy.
6
If you are using frozen spinach in a box, put it in the microwave for about 5 minutes with the tiniest amount of water, covered.
7
Drain the water and then either press all the water out using a towel or put the spinach in a sieve and smash out all the water with a spoon.
8
Combine everything together, give it a good mixing and pour into the crust.
9
Bake for 35-45 minutes at 375 degrees until set.

Enjoy!
