It's potato time
Definitely potatoes! You can make mashed or baked potatoes, French fries, potato wedges, potato chips ... the options are endless AND delicious.
What more can I say? I'm a big potato fan.

I wouldn't mind eating only ice cream for the rest of my life because there are so many flavours! Chocolate chip, Belgian chocolate, Rocky Road, Cookies and Cream, strawberry, vanilla ... yum, yum. And have you heard of bacon ice cream? It exists.

Without a doubt, I would choose fruits, the yummiest food on this planet. They come in a mouthwatering variety - savoury, sweet, creamy, juicy, tangy … the list goes on. Fruits are good for your health, too. They are a good source of vitamins and minerals, and can reduce your risk of heart disease and cancer. I wouldn't be able to function properly without my daily dose of fruit!

Tofu, tofu and more tofu. You can create so many different dishes from bean curd and they all taste great. You can make good appetisers (chilled tofu), main courses (ma po tofu) and even desserts (tofu pudding). Because tofu is made from soybean, it is also very healthy. I wouldn't mind eating it every day.

Piece of mind
Pizza, for sure. You could have all kinds of toppings - for example, pepperoni, pineapple, ham, bacon, cheese - so you'd never get bored of it. Plus, because it comes in individual slices, you can save some for later.

Keeping it local
If I could only eat one type of food for the rest of my life, I would definitely choose dim sum. I love the wonderful flavours, and always feel blessed when eating the small but delicious bites.

It would have to be kimchi. Deliciously spicy, it leaves a soothing taste in the mouth!
Gerald Koh, 16, West Island School
I would choose cereal with milk. This low-fat diet would contain enough vitamins and minerals to help me survive, and prevent me from becoming overweight.

All about that beef
I would choose beef. I love eating the meat in all its different forms, like steak. There are many ways to cook it - well-done, medium-rare or rare - and it contains iron, which helps prevent anaemia. Plus, it's not seasonal, so can be bought all year round.

Set up for life
It would probably be Soylent, a drink that has been called a "staple meal". It has all the nutrients required for an adult.
I'd be able to live on it for the rest of my life, as some people already do.
