Allow the bread dough to rise to double its size.
Form 24 small balls of dough.
Roll the balls in olive oil and form in a wreath shape on a baking sheet or several layers of aluminum foil with 1 circle of 10 balls and another adjoining circle of 14 balls.
If desired, top with sea salt.
Place a glass filled with hot water and covered in olive oil into the center of the wreath. Cover the glass and rolls with plastic wrap and then a dish cloth.
Allow to proof until double in size...about one hour.
Preheat oven to 375 degrees.
Brush the dough with the pesto.
Tuck in the fresh rosemary sprigs and tomatoes.
Bake for 30 minutes or until the bread is a deep golden color.
Remove from the oven and let cool.
Optional, serve with dip or hummus in the center of the wreath.
