The West Coast is full of groves and gardens of fresh fruits and vegetables. These ingredients when prepared correctly are full of vitamins, minerals and nutrients. Furthermore, these ingredients are naturally low in calories.
The great thing about eating foods grown locally is that they not only taste much better but also are still rich in vitamin C and folate (when produce is shipped they lose some of these nutrients).
With the wide selection of fresh fruits, grains and vegetables it is fairly easy to eat a vegetarian diet. Although when eating out vegetarian be sure to avoid high fat cheeses. Be sure to request vegetables grilled or sautéed in garlic and olive oil and to hold the cheese or go light on the cheese.
