This casserole is perfect for using leftover chili from the night before.
For a meatless version, simply skip the ground beef and use vegetarian chili.
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days.
Reheat in the oven to keep the tater tots crispy.
This is one of those dinners my daughter asks for again and again, which tells me it belongs in our family cookbook forever.
