What do Ashkenazim eat during Passover?

Matzoh, meat, fish, vegetables, fruit, eggs, dairy products, most kinds of nuts, and most beverages. All beverages, meats and processed foods need to be labeled Kosher for Passover, with trustworthy supervision and not containing Kitniyos (legumes). Today there are thousands of canned and processed foods which have strict Passover supervision. Several decades ago, the answer would have been: buy veggies and prepare them yourself.
