Spread pesto (1/2 tablespoon per slice) on each piece of bread. Add the cheese, tomato slices, and bacon (if you want) on two of the slices. Put the rest of the bread on top, making sure the pesto sides face the filling.

Butter the top slices, turn the sandwiches over, and give them another 2-3 minutes. When the bread’s crispy and the cheese is gooey, they’re ready! Let them cool just a little before slicing and eating.
