Technically speaking, tomatoes and chilis are fruits, while strawberries are not fruits (they are fruit clusters - each "seed" is an individual fruit). This is such a point of contention (apparently) that there's a whole "culinary" vs. "botanical" fruit distinction made.

Logically, eggs are meat. It's a giant animal cell. Culinarily speaking, meat refers to the tissue of mammals, particularly muscle tissue from pigs and cows and other ungulates. Fish usually excluded, poultry is often excluded, and offal may be excluded as well.

It's for the same reason why we call blackberries and strawberries both fruits (even though they are not). Culinarily speaking, they're similar. Used in a similar way. Deer, beef, and pork are interchangeable in many recipes. Beef, chicken, and salmon, are not.
