You don’t usually buy chocolate to get your protein dose though. Per kilo, dark chocolate is half the impact of beef. And a serving of chocolate is not the same mass as a serving of meat.

Edit: tofu is soy-based and can be added

Money aside, beef has a horrible environmental impact. Pork (as found in hot dogs) is way better.
