Hiya, if you don't eat any other types of veg or salad all day then you can have 3 cups of salad. Especially as it's spinach as this is quite low anyway on the carb front. Tell them you would like a dressing of just olive oil - you might find they already have it on the table, and if it's a traditional italian place then you'll find the wonderful taste of the fresh parmesan, spinach and olive oil will just mingle to make lovely yummy taste!! YUM YUM
