I put this together at the request of a friend.
The nice thing about this recipe is much of it can be done the night before. Also it's fun to let everyone customize their popover to suit their liking, than just 15 minutes in the oven and breakfast is served!
This can be done the night before. Cook and crumble sausage, cook and than crumble bacon. Lightly sauté green peppers, and onions in small amount of olive or canola oil. Store covered in the fridge till morning. I pull the puff pastry from the freezer and put in the fridge overnight.
In the morning take items stored in fridge out and set aside. Scramble eggs in butter or oil, but you want them to be scrambled soft so they don't dry out in the oven. Lightly sauté the hash browns in small amount of canola oil.
Make gravy. Using sausage drippings and butter, heat till they are sizzling. Add flour and cook for 7 minutes, this will cook the flour giving you a smooth gravy. Slowly add milk, stirring constantly till it reaches your desired thickness. You want this gravy to be on the thicker side.
Prepare cheeses and anything else you want to add to your popovers. Take puff pastry out of fridge and open each sheet. On a lightly floured surface roll out puff pastry till it's a 12"x12" sheet. Now cut each sheet into 6"x6" squares.
Preheat oven to 400 and put parchment paper on baking sheet. Set out all the fillings, so your family and guest can select the fillings they want in their popover. On a plate place one square of puff pastry and add the fillings you want on yours just on one half of the pastry. Now tap edge of pastry with a small amount of milk and seal the edges and lightly press edges with a fork to seal.
Now transfer each onto your baking sheet. You can write names on the parchment so not to mix them up. Bake at 400 for 15 minutes or till golden brown. Now garnish as desired, you can even pour warm gravy over it if you like. Now just enjoy!
