Tips from the Pillsbury Kitchens
If you’re destined for a potluck, make, bake, and freeze the casserole in a 13×9-inch foil pan. Thaw in the fridge the night before so you can just reheat it before heading to the party.
Tear up a bunch of fresh cilantro for sprinkling on each serving, along with setting out a bowl of sour cream or fresh lime wedges for a little tang to complement the richness of the dish.
