I substituted olive oil for the veg oil.
I used beef loin steak cubed, you could probably use any cut, just simmer it until tender.
I ended up using the whole 6oz can of tomato paste for added flavor, adjust to your liking.
We didn't have turnip so we substituted 2 med. potatoes.
I substituted 2 cloves minced garlic for the powder and sauteed it with the onion.
