Fresh salmon fillet can be cooked either in the oven as a baked dish or on the barbeque.
If baking in the oven, then it is best with the skin off – but if done on the barbeque, leaving the skin on and cooking it until it is crispy adds greatly to the flavour. The skin of course has its own nutritional value.
The secret with ratatouille is to dice the individual vegetables fairly finely and then to sauté them separately in oil in a frying pan as opposed to adding them all together in a saucepan. The latter results in steaming or boiling the vegetables and as a result quite a lot of their flavour is lost in the fluid.
