YO! Philly Cheesesteak Pasta in the Instant Pot

I tried something new in my magic pot tonight, an adaptation of another one of those recipe videos that was going around Facebook, called Philly Cheesesteak Pasta. It turned out well, but it basically tastes like Beef Stroganoff. (That's okay. I like Beef Stroganoff. Tee hee.)

Brown in a large skillet over medium heat in two tablespoons olive oil:
1 3/4 lbs. stew meat (I used chuck)
1 teaspoon seasoned salt

Add browned meat to the IP. In the pan drippings plus one tablespoon butter, cook until tender:
1 large onion, diced
1 green pepper, diced (I prefer a Cubanelle)
4 cloves garlic, peeled and minced

Add the sauteed veggies to the pot, plus:
1 tablespoon flour
1 cup chicken stock
1 cup milk
1 tablespoon Worcestershire sauce

Cook on stew mode for 35 minutes, then let release naturally.

Leave pot on warm and add:
1 lb. penne, cooked to al dente and drained
1/2 cup milk
1 1/2 cups shredded cheddar
1/2 cup grated Parmesan
salt and pepper, to taste
