*I prefer to use Better Than Bouillon Beef and Chicken Bases for this, but you can use whatever kind you like.
**Prefer other ingredients such as mushrooms, olives, spinach or anchovies? Go for it! Always make dishes how you enjoy them and add your own favorites!
***A 1/2 pound pre-sliced fresh mozzarella was plenty enough to top each bowl. But. I happened to have just slightly more. So, to the last bowl, I cubed it, added it to the hot soup ladled into the bowl before topping with the regular amount of cheese and before broiling, and you get that whole "dip the spoon into the bowl, pull it up, and massive gooey stringy cheese trails!" Swoon worthy! But it's a LOT of cheese!!!! So that's up to you.
