Mexican Shephard's Pie

The hubby wanted me to make shephard's pie the other night but without the french cut green beans in it.What used to be one of his fave veggies has now turned into something he won't eat.Go figure! I didn't have many spare veggies on hand so I thought I would turn it into a mexican version by adding black beans and the leftover "happy husband chili" I had from the weekend.I mixed all that up and topped it with what cheese I had on hand and topped it all off with mashed potatoes.The guys ate it.Grandpa's even gone back a time or two for the leftovers.
