Cook's Tips:

Italian seasoning can be substituted for the Italian Seasoning Mix, if desired.

To make mini paninis, substitute half of a 16-ounce French baguette, cut into sixteen 1/2-inch-thick slices, for the Italian bread. Substitute six baby portobello mushroom caps for the large portobello mushrooms. Proceed as recipe directs; cut paninis in half with Bread Knife.
