- Cut out meat from large animals that have the most environmental impact
- Work your way down from number 2 until all you eat is poultry
On the other hand cutting out smaller animals first would have a bigger impact on suffering because you need more beings for the same amount of meat. So I’d just say to just reduce meat, whichever is easier first.
It doesn’t have to be delicious, but it should contain most of the essential nutrients, at least similar to the non-vegan options. “French fries with ketchup” doesn’t meet this requirement.
