hmmm

I think you forgot a couple of the most important elements of any 'real' Italian cooking.

1. chicken stock: you should saute the veggies in a 1/4 of chicken stock..this will add flavour and depth to the dish.

2. BUTTER!!!: it is impossible to make a great Primavera without a little butter.

From Karen:
Growing up Italian sauteeing in chicken stock was not ever done in my house. It is a good idea for low fat cooking though.
