Pressure Cooker Italian Beef Stew - cooking recipe

Ingredients

2 lbs lean beef (or 1 pound of each) or 2 lbs veal, cut into cubes (or 1 pound of each)
1 medium onion, sliced
1 garlic clove, minced
1 lb white mushrooms or 1 lb baby portabella mushrooms, cleaned and cut into quarters
3 -4 tablespoons olive oil (or oil of choice)
1 (28 ounce) can crushed italian plum tomatoes with liquid (or two 14 ounce cans of tomato sauce)
4 -6 carrots, cut into 1 inch pieces (about 1 lb)
5 large peeled potatoes, cut in half, then quarter each half
1 lb fresh green string bean, cleaned and cut into bite sized pieces (can use frozen, cut green beans)
1/2 cup dry red wine
1 bay leaf
1/4 teaspoon dried basil, crushed (optional)
1/4 teaspoon dried oregano, crushed (optional)
salt (to your taste)
pepper (to your taste)
1 1/2 - 2 cups boiling water

Preparation

I browned the meat with oil and onions in my PC, you can use a separate pan for browning if you prefer.
Add the mushrooms and garlic, and let cook until the mushrooms release their liquid.
Add the tomato sauce, wine, bay leaf and all seasonings EXCEPT salt.
Add a bit of water, maybe 1 1/2 to 2 cups (to bring ingredient level to just over 1/3 capacity of my PC).
Secure lid, bring to HIGH pressure and cook for 18-20 minutes.
Let pressure release NATURALLY (it took about 15-18 minutes in my PC).
Add potatoes and carrots, give all a good stir.
Secure lid again and bring to HIGH pressure, cook veggies for 4 minutes.
Quickly release pressure (with quick release valve) and test carrots & potatoes for doneness (they should still be a bit too firm).
Add the green beans and give all a good stir. Secure lid and bring the PC up to LOW pressure, and cook for 2 minutes.
Remove from stove, quick release pressure (with quick release valve), removed lid and give the stew a stir.
Carefully (very hot!) sample it, adjust seasonings to taste (I added a bit of salt).
If stew is too thick, add a bit of water to thin to desired consistency.
If stew is too thin, let stand for 5-10 minutes before serving.
