White Broccoli Slice

You're referring to "Fried Calamari" or "Fried Squid Rings"! They're a popular appetizer in many American restaurants. However, I think you might be confusing them with a different dish. Since you mentioned "white broccoli slice," I'm going to take a guess that you might be referring to "Broccolini" or "Blanched Broccoli Fritters."

Broccolini is a real food, but it's not typically served as slices. Broccolini is a hybrid of broccoli and gai lan (Chinese kale), with a similar taste and texture to regular broccoli but with a milder flavor. You can find it in some upscale restaurants, especially those serving contemporary American or farm-to-table cuisine.

On the other hand, Blanched Broccoli Fritters or White Broccoli Fritters might be what you're looking for. These are breaded and deep-fried fritters made from blanched broccoli florets. They're crispy on the outside and tender on the inside, often served as an appetizer or side dish in some American restaurants.

If neither of these matches what you're looking for, could you please provide more details or characteristics about the dish you're thinking of? I'd be happy to help you identify it!
