For the spicy candied bacon, add bacon in one layer on a rack. Place the rack on an aluminum foil lined rimmed baking sheet. Sprinkle bacon with cayenne pepper and brown sugar. Place baking sheet in oven.

Turn oven to 425°F. You want to put the bacon in a cold oven and allow it to bake as the oven preheats so the bacon candies properly! Cook for approximately 15-20 minutes (time may vary based on how quickly your oven heats up, so check it a couple of times). Remove from oven when done and cut slices in half. Set aside.

In a small bowl, whisk together ingredients for the garlic Sriracha mayonnaise. Set aside in the refrigerator.

Heat approximately 1/2 inch of vegetable oil in a small skillet over medium-high heat. Once the oil is hot, add one piece of sliced bread. Fry until golden brown on both sides, approximately 1 minute per side. Repeat with one additional piece of white bread. Set aside.

Toast remaining four slices of bread.

To assemble the sandwiches, start with one piece of toasted bread as a base. Spread the toasted bread with an even layer of garlic Sriracha mayonnaise. Top with a layer of lettuce, tomato and then bacon. Top with a piece of fried bread and repeat the layers of mayonnaise, lettuce, tomato and bacon. Spread half of the mashed avocado on a piece of toasted bread. Place bread avocado side down to top off the sandwich.

Cut sandwich in half and insert toothpicks into each half to hold them together. Serve immediately.
