The perfect formula for a summery baguette sandwich!
In a small bowl mix together the mayo and pesto and set aside.
Slice the baguette length-wise and slather both sides with the pesto mayo. Layer the mozzarella on one side and toast or broil until cheese is melty.
Thinly slice the tomatoes and layer over the melted cheese. Sprinkle with salt & pepper.
Fold sandwich up and cut into as many pieces as desired.
Wrap sandwiches in paper or plastic and it will be good for several hours.
This "recipe" is a loose guide to making one of my favorite sandwich combos. You can adapt it however you'd like though, adding turkey or proscuitto to this combo as well!
