Step 1

Preheat oven to 400 degrees. Cut the ciabatta rolls and arrange them sliced side up on a rimmed baking sheet.

Step 2

Mix together olive oil, garlic, and sea salt. Brush the cut side of each roll with the olive oil mixture, then toast at 400 degrees for 6 minutes.

Step 3

While rolls are toasting, slice the tomatoes and cheese, and mash the avocado.

Step 4

Remove the baking sheet from the oven and turn off the oven. Spread each roll thinly with mashed avocado.

Step 5

Top each open faced sandwich with cheese and a couple of tomato slices.

Step 6

Return the baking sheet to the oven and broil on high for 4-5 minutes, or until cheese is browned.

Step 7

Sprinkle on a little dried basil, drizzle sandwiches with a touch of balsamic vinegar, and serve.
