I find appetizers to be merely an aesthetics, because I don't really notice increase in my appetite after eating them. Instead I feel that it decreases as I feel that I am not that hungry anymore. So I don't order them. Besides, they already add to the calories, and if they really work as appetizers, then I will definitely gain more calories, and if I don't use them, weight.
Well that's because appetizers have totally changed. The point of an appetizer (like bread) was to stimulate your taste buds, making you more hungry for your meal. But portions are so out of control that appetizers are basically whole meals now! So I don't think that appetizers (the way they exist today) serve their original purpose. You're correct. lol
Appetizers usually fill me up pretty quickly, after I eat a few I can't handle dinner or anything else actually lol. My favourite appetizer is definitely one that would have cheese and spinach in a phyllo wrap. Yummy! Haha. Whne I go to a restaurant and order them, they have pretty large portions as well and so I don't need to spend much on the actual main course.
