Peppers — The general rule of thumb is that if there are seeds, it's a fruit.

Eggplants — These are berries, which are defined as "fleshy fruit that have multiple seeds on the inside, embedded in the flesh of the ovary."

Tomatoes — Like eggplants, tomatoes are fruits because of their many seeds.

Cucumbers —Yup, these too are fruits thanks to their seeds.

Avocados — You may consider avocados seedless, and thus a veggie, but their pit are regarded as one giant seed, making them a single-seeded berry.

Olives — These are considered fruit in the same way avocados and their single seed are.

Squash — Again, seeds. Butternut squash, the sweetest of the squash family, actually makes sense as a fruit.

Pumpkin — This fruit is considered a winter squash, and is thus also fruit.
