Set 30-35 (or more) charcoal briquettes to fire in a pile or in the charcoal chimney. Set your cast iron Dutch oven near that burning pile of briquettes and start to warm it up.
Heat the Dutch oven for frying. Place the 12-inch cast iron Dutch oven over those 30-35 (or more) briquettes and really heat it up well. Don’t add your butter yet. Once the pot starts to show wisps of smoke, add the 2 tablespoons of butter, and let it heat up and “toast.”
When the butter and the pot are very hot (don’t burn that butter), add your pork and a sprig or three of rosemary. Sear the first side very well. Then, turn the pieces of meat and sear the other side.
After you have seared your pork, place the hot meat nearby on the upside-down lid or in another Dutch oven to keep warm. Remove the stems of rosemary.
Pour in about 1 cup of seasoned breadcrumbs over whatever bits and pieces are left from searing the pork and butter is left in that pot.
Pour in about ½ cup of beer at a time. Mix the beer in with the breadcrumbs and create a batter-like mixture about the consistency of thick pancake batter.
Return the seared pork to the pot.
Top the pork with the chopped potatoes.
Pour over the cans of cream of mushroom soup and roughly spread about the top of the potatoes.
Add the chopped green bell peppers to the top of the entire recipe/mixture.
Cover the pot and set the Dutch oven to bake. Place 8 hot briquettes around the circumference of the bottom and place 16 hot briquettes on the top.
Pork is considered done at 145°F / 65°C. Bake until the pork has reached temperature AND the potatoes are cooked.
Once the dish is done, remove the lid and pour a thin layer of breadcrumbs over the mixture. Remove all of the heat from the bottom of the Dutch oven and place any remaining briquettes over the top of the Dutch oven (all the heat on top).
Once the breadcrumbs on the top are toasted, remove the pot from the heat and ENJOY!!
