1.5 lbs shaved beef or thinly sliced steak (top sirloin or ribeye)
1 1/2 Tablespoons tapioca flour (you can also sub 1 T cornstarch)
1 1/2 tsp garlic powder
1 tsp onion powder
salt + pepper
1/2 yellow onion, thinly sliced into strips
1 shallot, thinly sliced
1/2 red bell pepper, thinly sliced into strips
1/2 green bell pepper, thinly sliced into strips
1 Tablespoon butter
4 cloves garlic, finely chopped or minced
1 Tablespoon Worcestershire sauce
6 slices provolone cheese
Hoagie rolls or slider buns, for serving, optional
Fresh jalapeños, for serving, optional
Instructions
Pat dry your shaved beef or steak and then toss with tapioca flour, salt, pepper, garlic powder, and onion powder. Set aside.
Heat a few Tablespoons avocado oil (or olive oil) in a medium sized cast iron skillet over medium high heat. Add the onion, shallots, and peppers, and cook for a few minutes and then using tongs, toss around and cook another few minutes until soft and slightly charred; about 7 minutes total.
Add in butter and minced garlic and cook another minute or so until the garlic is fragrant. Transfer the sautéed veggies to a bowl on the side.
Using the same skillet, add a little more oil if necessary and make sure the skillet is still very hot, add in the beef. Do this in batches if needed so not to overcrowd the pan. Let be for a minute or two to get a nice sear and then cook a few more minutes until cooked, and then pour in the Worcestershire sauce and toss to coat.
Add the onion & peppers back in and toss to combine everything together. Reduce heat to low and top with 6 slices of provolone cheese.
You can either add a lid and allow the cheese to melt, or my personal favorite is to pop under the broiler for a few minutes to get the cheese nice and golden.
Add the pepper and cheese mixture to toasted rolls and enjoy!!
