Preheat your oven to 400°F.
Pre bake your premade pie shell 8-10 or golden brown (or follow the instructions on your premade pie shell).
Once your premade pie shell is ready, evenly arrange the tomato slices into the premade pie shell.
Season with salt, pepper, basil, and chives.
In a medium bowl, stir together the mayonnaise and grated cheese until smooth.
Spread this mixture over the tomatoes.
Bake for 30–35 minutes, or until the cheese is melted and lightly browned.
Let cool for 30 minutes before cutting into it.
