Corey calls this one "Mexican Shepherd's Pie"

Boil halved baby red potatoes (or really any kind you want)
Brown Chorizo Sausage with quartered button mushrooms
Put sausage and mushrooms into small baking dish
top with 8-16 cubed oz of melting mexican cheese (I like pepperjack, but you can go less spicy if you want)

Bake at 350 until bubbly and golden on edges (like 10-15 min)

Serve on slightly squished potatoes

Or - Put slightly squished cooked potatoes on bottom of baking dish, cover with sausage mixture and cheese and bake all together.

Very Tasty
