Cook the bacon in a skillet until it reaches the crispiness you desire. Drain the bacon on a paper towel lined plate and set aside until needed. Wipe out the excess grease with another paper towel.
Coat both sides of each mushroom with olive oil, then sprinkle both sides with salt and pepper. Using the same skillet as the bacon, add a little oil (if needed) and add your mushrooms. Cook the mushrooms until they are tender, but still firm, approx 4 minutes per side. Remove from the skillet and place on a plate until needed.
Using the same skillet, adding oil if need be, fry your eggs. Sprinkle some salt and pepper on the eggs while they cook.
When the eggs are almost finished cooking, assemble your Open Face Mushroom BLT's. Start with the mushroom on the bottom, topped with some arugula, then the tomato, then the bacon, then the avocado, then finally the fried egg.
Cut into the yolk so it drips down on top of the other ingredients, then enjoy!!!
