If there was ever a time to say: "You sound poor" this would be it (although I am well aware that you are a happily married and successful guy).
If tins and packets can be substituted for a can, I pretty much live off tinned salmon and oatmeal.
In the spirit of the thread:
Appetizer: Heinz Canned Beans and Bacon
Main Course: Canned Chili + Chef Boyardee (combine both for a meat based pasta)
Dessert: Can of Pumpkin Pie Filling (Which is actually awesome if you like pumpkin pie).
As a bachelor who travels quite a bit, I have been known to eat both beans and fish straight out of the can with a spoon.
