 are soft but still slightly crunchy. Add the squash & pepper. Cover &
 cook for 20 minutes.  Add the tomatoes & cook another 3 to 5 minutes.
 Cool. Stir the yeast into the water & let proof for 10 minutes. Add
 the biga & mix well. Add the rest of the olive oil. Stir in the
 cooked vegetables. Add the flour & salt slowly, mixing until the
 dough comes together. Knead with wet hands until the dough is form,
 velvet & elastic. Place dough in an oiled bowl, cover & let rise

 into long cylinders. Place on floured baking sheets, cover & let rise
 until well doubled, about an hour. Preheat the oven to 400F. Bake for
 35 to 45 minutes, until golden.
