Set your air fryer to bake at 350F for 5 minutes (you can also use your oven for this, I just use my air fryer to save on electricity)
While your air fryer is heating up, cut your bread into slices, then top with parmesan cheese. When your air fryer has preheated, pop these in.
While the bread is baking, mix together the tomato, basil, red pepper flakes, salt, pepper and balsamic vinegar (option to add in at this point or drizzle the balsamic vinegar on top after).
Once the toast is done, top with your tomato mixture. Drizzle with balsamic vinegar, if you did not add it to the tomato mixture and enjoy!
