Preheat Big Green Egg to 400°F setup for direct grilling
Place a 12” cast iron pan into the Big Green Egg to preheat
Chop the onion and pepper, mix with 1 Tbsp of Olive Oil and 1 Tbsp of Dizzy Pig SPG, mix well and add to the cast iron pan cook for 3 – 5 minutes stirring frequently until the veggies are softened the remove
Take the sliced and diced steak and toss with 1 Tbsp of Olive Oil and 1 Tbsp of Dizzy Pig SPG add to the cast iron pan
Cook 5 minutes or so until you no longer see any pink
Add back in the veggies and mix well
Close top and bottom vent and cook another 3 – 5 minutes then top with the provolone cheese slices
After a few minutes the cheese will be melted, and it is time to remove the cast iron pan
