Yes. A few weeks ago, some coworkers and I mapped out the entire sandwich taxonomy. You attain sandwich nirvana once you derive these definitions:

1. Hot dog is a taco.
2. Taco is a subcategory of sandwich.
3. If the sandwich contains an additional piece of bread inside of it, it is now a lasagna.
4. Lasagna is a subcategory of sandwich. 🤯

Now it all makes sense. Be at peace.
