*Made for PAC Spring '08* Yummy! We really enjoyed this variation of a grilled cheese sandwich. The pesto and provolone cheese really kicked the flavor up a notch. I used cracked wheat sourdough for the bread. Also, I didn't have any pesto sauce, so I added a small amount of pesto to some mayonnaise and this worked perfectly. I did add some tomato slices, too. My family loved this and gave it 2-thumbs up. Thank you for sharing this great recipe.
