This is our favourite sandwich to have for dinner on a lazy weekend. I like to serve it with sweet potato fries and a Caesar salad. Mmm . . . mmm . . . scrumptious!

Ingredient Checklist


Instructions Checklist
  • Season steaks with salt and pepper; allow steaks to come to room temperature, about 15 minutes.

  • Heat oil in a skillet over medium heat until very hot; lay steaks in pan and cook until they are beginning to firm and are hot and slightly pink in the center, about 5 minutes per side. An instant-read thermometer inserted into the center should read 140 degrees F (60 degrees C). Transfer steaks to a warm plate; cover and let rest, about 10 minutes.

  • Melt butter in same pan over medium heat; stir in mushrooms and peppers. Season with salt and pepper; cook and stir until tender, about 5 minutes.

  • Set oven rack about 6 inches from the heat source and preheat the oven's broiler.

  • Toast buns under the broiler until golden, about 2 minutes. Divide mozzarella cheese over bottom halves of buns; return to broiler until cheese melts, about 2 minutes.

  • Slice steak very thinly. Pile steak slices over cheese-topped bun halves; top with mushrooms and peppers. Spread mayonnaise on top halves of buns; place over sandwich.

Cook's Notes:

If you like spice, add some Sriracha or adobo sauce to your mayo.

You can use your favourite cheese: mozzarella, Monterey Jack, Cheddar, or Swiss.

this is my fav go to sandwich! it sooooo tweakable (lol is that a word?). it never turns out the same way twice. sometimes i change up the seasoning on the steak and may season up the mayo with hot sauce or mustard or whatever i feel like at the time. sometimes it's the bun! it's very delicious and nutritious (i'm throwing that in for good measure lol) AND deeply satifying! Enjoy Read More

This was Awesome! I used leftover steak from last night which i just heated through. I used a red bell pepper from my garden (1st one picked) and added some sliced red onions and garlic to the mushroom mixture. I love how you can really make this sandwich your own..i used BBQ sauce in place of mayo and Monterey Jack cheese because that's what i had on hand. Thanks for the Delicious recipe..will be making this again! Read More
