Open-Faced Tomato and Mozzarella Sandwich with Basil Aioli

This open-faced tomato and mozzarella sandwich with basil aioli is one of my favorite sandwiches! Years ago, when visiting my husband’s hometown, we stumbled upon a great restaurant called Bistro 45. I made this open-faced sandwich for lunch today, and the second half made a great snack for my kids after school. This delicious open-faced sandwich pairs nicely with tomato soup with pesto.

How to Make an Open-Faced Tomato and Mozzarella Sandwich with Basil Aioli
Preheat the oven to broil on high. Place the rack in the upper-middle portion of the oven.
Prepare the basil aioli by combining the mayonnaise, minced basil, and minced garlic; mix until well combined.
Slice the baguette in half lengthwise. Slather each half with some basil aioli, to taste. Sprinkle the top of each baguette half with some shredded mozzarella cheese.
Place the baguette halves on a baking sheet, then place under the broiler for 2-3 minutes, watching carefully, until the cheese is melting and starting to turn golden brown.

My kind of sandwich.
I’ve made sandwiches like this, but I usually put a little more cheese over the tomatoes. It has to rate as one of the greatest lunches you can have in a hurry!
