Where to Learn Taiwanese?

I'm starting to learn Chinese and it's very fun once I got past my crippling fear of the tones. I even get along with Chinese characters... at least traditional Chinese characters. The simplified ones look unfamiliar to me which is why I decided I wanted to learn the Taiwanese variety of Chinese.

The problem is that, living in the UK, everyone teaches only Beijing Chinese. I'm still a beginner. I can hardly put together simple sentences like "馬吃了我的飯". It's probably very similar so far, but I wanted to ask you if you know of some good online resources for an English speaker to learn Taiwanese?

For now, I'm learning Zhuyin and writing all my notes in traditional characters, but I want to include specifically Taiwanese vocabulary once I'm more advanced so my knowledge of the language is more consistent and less of a messy amalgamation.
