100 gr soybeans
200 gr carrots

Place a teaspoon of the filling in each one of the square pieces of dough.

Warm up in a pan the vegetable stock and add the won ton. Let them boil in medium heat for about 10 min (although it might take more than that)
Put the won ton in a bowl and add some of the stock.
