Best Beef Stew for Kids

This is the best beef stew recipe for kids...mine devour the lot, even Cricket who doesn't fancy most cooked food.  The recipe is adapted from the Feeding Kids cookbook by Netmums.  I tend to buy really good steak to put in and then it is a real treat with meat that melts in your mouth.  The cookbook has dumplings in the recipe and it is cooked in the oven.  Sounds yum, but this is a simpler version.

1Tbsp olive oil
500g stewing steak cut into small cubes
1 large onion chopped
1 garlic clove chopped
1Tbsp flour
500 ml beef stock
1Tbsp tomato puree
3 medium carrots, peeled and chopped
2 large potatoes, peeled and chopped
1tbsp balsamic vinegar

Cook the onion in the olive oil. Add the beef and cook till brown.  Add the garlic and stir in the flour. Add the stock, puree, carrots, potatoes and balsamic vinegar.  Simmer for two hours.  Serve with rice. and a green vegetable on the side.  Seriously delicious and simple to make.
