This comes from the April 2005 issue of Cooking Light. They recommend that you do not substitute bacon for the pancetta as the smoky flavor would overwhelm the peas. The unsmoked pancetta really balances the sweetness of the new peas. You can substitute frozen petite green peas for the fresh.
This casserole is a great comfort food and makes a good impression if cooking for company. It only has 3 steps to prepare! Who can beat that? I like to double this recipe and freeze one for a future dinner. This is a favorite of my hubby.
