Cook the diced smoked sausage in a 12-inch cast iron skillet (see note) with the butter until it is lightly browned.
Scoop out the browned sausage with a slotted spoon and place it in a bowl. Set that aside for now.
Cook the peppers and onion in the drippings until they are tender and the onions are slightly golden.
Add in the minced garlic, oregano, red pepper flakes, diced tomatoes, kidney beans, water, salt, and pepper. Return the smoked sausage to the skillet. Stir together.
Allow this to simmer on low heat while you prepare the cornbread topping.
Cornbread Topping
Combine the all-purpose flour, cornmeal, baking powder, salt, and baking soda in a mixing bowl. Stir together.
In another small bowl, beat the egg. Then add in the buttermilk and melted butter, stir to combine.
Add the buttermilk mixture to the dry ingredients. Stir with a whisk until just combined.
Stir in the Parmesan cheese.
Use a spoon or spatula to spread out the sausage mixture evenly in the skillet.
Spoon the cornbread topping all over the top of the sausage mixture.
Bake for 20-25 minutes, or until the cornbread is slightly golden around the edges and tests done with a toothpick.
Allow the cobbler to rest in the pan for 5 minutes before serving.
Enjoy!
