Toast the 2 pieces of whole wheat toast until the bread is just golden brown.

Cut the avocado in half lengthwise. Remove the pit from the avocado and discard. Remove the avocado from the skin and place the avocado flesh into a medium bowl and mash it with a fork and a squeeze of the fresh lemon juice. Season with salt and pepper as needed.

Divide the mashed avocado on top of the 2 pieces of toast, followed by a slice of tomato, and then 2 pieces of the bacon.

Sprinkle with salt and pepper and serve immediately.
