Preheat oven to 450, line a baking sheet with parchment paper.
Chop bacon into 1/2″ strips, cook til almost crispy. Use a slotted spoon to remove bacon from pan and set aside, reserving drippings for other uses (May I recommend our “Epic Popcorn?).
Whisk eggs and scramble just until set. Remove from heat and set aside.
In a medium sized bowl, mix together flour, baking powder, salt, and oregano.
Measure shortening into the same bowl, and cut into the dry ingredients using a pastry cutter or fork(s). The ideal is to work it in until it’s evenly distributed throughout, in very small pieces. Add a handful or two of the bacon, stir gently to distribute.
Add milk, stir until dough comes together. Don’t over stir or beat it.
On prepared baking sheet, spread dough out, forming a crust that is of even thickness – between 1/2″ – 3/4″ thick. Evenly distribute scrambled egg over the crust, and top with mushrooms, green peppers, and remaining bacon (use whatever amounts of each that you like). Scatter cheese over the entire pizza.
Bake for 12-15 mins, or until dough is cooked through.
