How I should parse/translate てなことで at start of sentence?


The sentence is

> てなことで、修行なんてしなくとも、ただ飯を食っているだけで強くなれるんだな。

Google translates first part as "By the way". But I can't find any information
how it should be parsed. I think its probably "てな こと で", but only translation
of "てな" seems to be this, which doesn't match:

> てな; ってな; てね; ってね (prt) (used at end of sentence) (apparently) that's what
> it's like, isn't it




This てな is a highly colloquial variant of という or というような. てなことで is the same as
ということで, which in this context means "therefore" or "for this reason", not "by
the way".

> **てなことで** 、修行なんてしなくとも、ただ飯を食っているだけで強くなれるんだな。  
>  **Therefore** , even if you don't train, you can get stronger just by
> eating and spending time.
