Pan Fried Stem Lettuce 清炒萵筍

It is great to live in a city which like Hong Kong, we don't have agriculture but on the other hand there are many imported vegetables around the world and the mainland China :)
Recently, I found the stem lettuce from the Northern China in the local market, of which I don't know how to cook... so I search on the website that can be eaten as salad and pan fried.

Recipe:  
1 pc (600g)                     stem lettuce in slice
2 pcs                              garlic in slice
olive oil and salt

Procedure:
a)  Wash and cut the stem lettuce in fine slices;
b)  Pour 1 tbsp of oil into the pan, first pan fried the garlic, then the lettuce until soften; seasoning with salt, so easy and done!

很是幸運住在香港這個城市，雖然我們沒有農作業，但在另一方面我們有許多由歐美和中國大量進口的蔬菜！
最近我發現在本地市場，有從中國來的萵筍，而我不知道怎麼做？在網上我尋找，原來莖和葉也可食用，發現可以做沙拉和炒。

食譜：
1個（600克）         萵筍切片
2粒                          蒜切片
適量橄欖油和鹽

程序：
a）洗淨萵筍莖，後切細片;
b）把1湯匙油倒入鍋內，先炒大蒜，然後萵筍片，直到軟化; 以鹽調味，這樣容易！
