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 1/4 cup of the burrata on top of each.
In a small skillet, heat the olive oil over medium high heat. Add the tomatoes and saute for 3-4 minutes until they just start to burst. Add the garlic and saute for 1 minute more until fragrant. Remove the tomatoes from the heat and season with salt and pepper. Add a few tomatoes on top of the burrata.
Sprinkle with salt and pepper and serve immediately.
