Which of the following foods would lacto-ovo vegetarians not consume?

Lacto-ovo vegetarians include dairy products and eggs in their diets but do not consume any form of meat, including fish. Halibut is a type of fish, therefore it does not align with the dietary restrictions of someone following a lacto-ovo vegetarian regimen. Foods such as egg salad, vegetable stir-fry, and cheese pizza are all acceptable options for lacto-ovo vegetarians as they can include eggs and dairy while being free from meat and fish. This classification emphasizes the importance of understanding dietary preferences and restrictions when discussing vegetarian choices.
