1 lb sirloin steak strips Your meat need to be a bit fatty. It helps with flavour and also it avoids the meat to get dry.
salt and black pepper to taste
2 tablespoons olive oil
10 oz white mushroom sliced
3 garlic cloves minced
1 tbsp balsamic vinegar
2 teaspoons yellow mustard
1/4 cup soy sauce or coconut aminos (for keto, low-carb, paleo and Whole30)
2 teaspoons arrowroot flour or cornstarch (if you're not doing paleo, Whole30 or low-carb)

Set a 6-qt Instant Pot® to the sauté setting. Season the meat with salt and black pepper. When the pot is hot, add olive oil and beef. Cook for about 5-7 minutes or until the meat is browned on all sides. Remember to stir occasionally.
Then, add the mushroom, garlic, balsamic vinegar, yellow mustard and coconut aminos to the pot.
Put on the lid, lock it and check to see if the vent is at sealing. Then, select manual setting; adjust pressure to high, and set time for 15 minutes. Mine took about 15 minutes to reach pressure. After the 15 minutes is up, let it naturally release pressure for 10 minutes. Then, do a Quick Release, which means move the valve to venting to release the steam. When all the steam is gone, open the instant pot and add the arrowroot flour.
Mix all well and serve with mashed potato. Enjoy!
