Here's what you do.
Step 1: Step One: Finding Your Ingredients
Now where can you get these all for free? Why anywhere that sells food! Just walk into any fastfood joint in America, walk up to the counter and ask of cup of hot water. If they make you pay for it just rant and rave a little, They will just give it to you to go away!
So on your way out hot the condiment bar.
Here is everything you need to make Hobo tomato soup.
Pocket as much Ketchup, Sugar, Crackers, salt/pepper as you can before escorted out.
If you have some left over you can make soup again by boiling water in a tin can over a small fire or discarded lighter.
Step 2: Making Soup
use the salt/pepper and crackers added for taste and those important calories!
