Here’s where it gets ironic. We, as a species, have decided that “fruit” means “sweet” and “vegetable” means “savory”. That’s it. That’s the whole rule for most of us. (Sorry, science.)
Think about it: we put strawberries on pancakes, but we put bell peppers in stir-fry. We mash bananas into bread, but we mash potatoes with butter. Nobody is putting a raw onion in a fruit salad. Ew.
This is why the avocado is such a rebel. It’s a fruit, it has a big seed, but it’s creamy and fatty and goes with lime and tacos. The avocado doesn’t care about your rules. It lives its best life on toast.

The Legal Loophole (Yes, Really)
You think it’s just a debate for bored cooks? Oh no. In 1893, the U.S. Supreme Court had to decide: Is a tomato a fruit or a vegetable? I am not joking. Look it up (Nix v. Hedden).
The court ruled that for trade and tax purposes, the tomato is a vegetable. Why? Because people eat it with dinner, not dessert. That’s it. The law literally ignored biology to keep things running smoothly at the grocery store.
So, now we have a system where the botanical definition says one thing, and the legal and culinary definition says another. It’s like the plant kingdom is running a con game, and we’re all just paying for the tickets.
