In my very early days of vegetarianism I started out by just not eating 'meat'...so that meant I would consume chicken broth. I know, sounds ridiculous now, but some of us need to take baby steps in order to achieve our goals. I didn't take me long to realize that if I were going to consume chicken broth that I wasn't a vegetarian. Little by little I gave up any foods that contained animals/by products, including dairy and eggs. There's a lot to process when it comes to eliminating animal ingredients from your diet. If it weren't for Veggieboards I don't think I would have come this far. Read, read, read and educate yourself!
you can always take the 'do it yourself' route if chicken noodle soup is something you really like...you can make it with veggie broth instead...or even use simulated chicken broth that you can get at some specialty stores
and there are never stupid questions, it's always better to ask!
