Puff pastry dough is an inexpensive time-saver that gives simple dishes an elegant touch. Make sure you don't pick up phyllo dough by accident! They're similarly packaged in the freezer section of your grocery store, but they're not interchangeable. For this recipe I used 1 + 1/3 packets of the dough to fit my the large pan. Instead of prepared pesto I made my version with green and purple basil. I required a few more tomatoes and bigger squash than the recipe suggests, too. Next time perhaps braised artichokes or roasted asparagus would be good! I forgot to top mine with the chopped olives, and it could have used the extra tang since the goat cheese was so mild.
