For an extra layer of flavor, try adding a pinch of red pepper flakes to the vegetable mixture. Feel free to substitute other cheeses you enjoy, such as Gruyere or Monterey Jack. If you don't have buttery round crackers, any type of cracker will work – just adjust the amount of melted butter accordingly. This casserole can be assembled ahead of time and baked just before serving. Perfect for potlucks and gatherings!
