Preheat the oven to 400oF.
Pour oil on the bottom of the 11x17 sheet pan and spread along the bottom and sides with the brush.
Add parchment paper to cover the bottom and sides of the pan with about ½ inch to an inch overhang.
Add oil to the parchment paper and spread as before along the bottom and sides.
Scoop the sardines from each tin with the fork and spread them along the entire bottom of the pan, leaving the oil in the tins.
Place the artichoke hearts on top of the sardines.
Crack as many eggs as will fit into the prep bowl.
Pour the craked egg into the blender.
Repeat until all 12 eggs are cracked and in the blender.
Add ¼ cup heavy whipping cream and salt to the blender.
Blend on low until the mixture is consistent.
Put the spinach/arugula mix into the blender and stir so the greens are all coated in egg.
Pull the top rack partially out of the oven and place the sheet pan onto it.
Carefully pour the egg mixture into the pan.
Pour the oil from the sardine tins over the eggs.
Push the rack back into the oven and bake for 20 minutes or until a toothpick inserted into the center comes out dry.
Allow to cool and cut into 12 equal(ish) pieces and serve OR prep for freezer storage.
