One of the problems that many parents face when raising children is they won't eat their veggies.

Twitter user ゆいにゃん Yuinyan (@yuionkure), who has two children, says she was saved by a product she bought at Daiso.

It was a microwave chip maker!

It's so easy to use. Just arrange sliced potatoes, yams, carrots, etc. as you can see in the image below, and heat them in the microwave. Not a drop of oil is required!

The veggie slices come out dry and crispy!

Cooking them like this concentrates the flavor of the veggies, heightening their taste.

These vegetable chips are also easy to make because there's no need to fry them in oil.

Yuinyan's 4-year-old daughter is happy to eat them plain, but those who want some more flavor can sprinkle some salt and pepper or other spices.

Many people reacted to Yuinyan's post, saying they found the gadget useful, and leaving comments such as: "It looks good for my kid who won't eat vegetables! What a great reaction from your kids!" Others admitted they had bought the gadget already and commented, "I tried making it with lotus root and it turned out delicious."

According to Yuinyan, carrots are difficult to make crispy and she struggles with them, but yams and sweet potatoes get crispy and are easy to make.

It seems that the moisture content of the vegetables and the thickness of the slices determine how crispy the chips get.

If you buy Daiso's microwave chip maker and try it at home, you can experiment and see what works best for you.

In Japanese Daiso stores, they cost 100 yen (about 83 cents US at the current exchange rate) plus tax, and are available at their online store here.
