This is great, satisfying meal for Father's Day, a hearty lunch, parties, or for gatherings of family and friends. High in protein because of the beef and cheese, there's also lots of nice veggies (red peppers, green peppers, onions, and shitake mushrooms) cooked right in!
Spread 1 T butter thinly on the cut side of each slice of sub roll
Broil the sub rolls, buttered side up, at 400 degrees for four minutes, then at 300 degrees for 1 minute, or until bread is nicely toasted. Set aside.
Prep the Veggies, Spices, and Meat
Measure the spices and avocado oil. Set aside.
Wash and Cut the veggies into thin slices, keeping separate. Set aside.
Let's Get Cooking!
Preheat the griddle to 350 degrees.
Add 1 T avocado oil to griddle.
Immediately add peppers and onions. Flip and stir frequently until the desired doneness, or until the onions are soft and begin to turn brown. (About 9 minutes)
Remove peppers and onions from the pan and set aside.
Add another T avocado oil to griddle.
Add shitake mushrooms, flipping and stirring frequently until desired doneness. (About 9 minutes)
Remove shitake mushrooms from pan and set aside.
Add another T avocado oil to griddle.
Add 1 lb shredded / sliced beef, separating slices and forcing them apart as they cook.
After 1 minute of cooking, sprinkle in all spices and apple cider vinegar.
Cook 2 additional minutes.
Add back in the peppers, onions, and mushrooms.
Mix everything together on the griddle, then spread thin.
Add 6 1-ounce slices of provalone cheese. (Boar's Head brand is one of my favorites.)
Place griddle cover on griddle and cook for 2 minutes. This should allow the cheese to full melt.
Turn of griddle heat and remove the cover. Using tongs with rubberized ends (to protect the nonstick grill surface), lift portions of cheesy steak off the griddle and onto the prepared sub roll, filling well.
Let's Eat!
Load up one of the broiled rolls with Philly Cheesecake mixture, which is now all melty and delicious. Enjoy!
