切咗既蔬菜(例洋葱,蕃茄等), 可以點樣保存到2至3日, 因為只煮2人飯= =

經驗話我知蔬菜在唔濕水和乾身的情況下會保存得較耐。
你其實可以切開d蔬菜後用密實袋或保鮮盒封好，唔好用保鮮紙，因為好難包得靚又唔可以再用~~~
如果包菜就用報紙包就最好囉~~

Hi, Onion 洋葱 can use the aluminium foil to wrap it tight and put into the refreigator up to 5 days. Tomato 蕃茄 can put into the container and put into refreigator up to 3 days. another vegetables (such as all kinds of bell peppers, spring beans, icebery, red carrot, broccli ...etc) can be stored in the vegetables area of refreigator up to a week.
normally all vegetables should be eaten at once, otherwise the nutrients will be lost soon.

為何你要將蔬菜(例洋葱,蕃茄等), 一次切幾日用？
蔬菜的最佳保存方法是保持原狀（連著皮），因為蔬菜的濕度對它的保存很重要。
如你已將蔬菜一次切幾日用，最好將它保濕、封好（可用密實袋或盒等）放入雪柜。但蕃茄不適合放過一天，用時才切也很方便吧，否則營養盡失。
