Tamales are really fun to make but somewhat labor intensive, so most people tend to make them in large batches. Which means you inevitably end up with leftovers. You can freeze any extras, of course, but this casserole is another delicious option for using up leftover tamales (especially ones that have been reheated more than once and are a bit dry). Roast your own poblano peppers (it's easy to do) and add them to this casserole for extra flavor. When making tamales, we often end up softening more dried corn husks than we actually need. We have to go to a special grocery store to buy the corn husks, so we like to save the ones we haven't used. Spread any leftover wet corn husks on a cookie sheet and heat them in the oven at 200 f for 10 to 15 minutes. Turn off the oven and leave the corn husk in the oven until they are completely dry and cool. Store them in a plastic bag until ready to use again.
