The recipe below is truly a dish for bacon lovers! Everyone's favorite breakfast meat features twice in this casserole: Once in the grilled cheese sandwiches that form the base, and once in the guacamole itself. The result is a rich, smokey dish that's sure to please for brunch, lunch, or dinner.
The casserole can be prepared in advance up to the baking step; simply cover the custard-soaked sandwiches with plastic wrap and store them in the fridge for up to a day. Be sure to remove the plastic before baking! The guacamole is best prepared just before serving, as avocados have a tendency to oxidize and go brown when exposed to air. But if you prepare all of the diced mix-ins in advance, it's easy enough to toss together, making this the perfect recipe for a party!
