have a finger in every pie

to be involved in and have influence over many different activities, often in a way that people do not approve of

(常指不受欢迎地)凡事插手，到处干预

从字面上看have a finger in the pie是“把手指戳进一个派”，派是让人吃的，平白无故被手插了个窟窿，这种行为还是让人非常讨厌的，它隐含的意思就是“什么事儿都愿意掺和进去，掺和一脚”。

比如说我的老板特别不敢放权，老不放心我，所以他总会这么做：

My boss always wants to have a finger in the pie. He doesn't think we can do it by ourselves. Then, why did he hire us?

我的老板总是想插手每件事。他认为我们自己做是做不好的。那他为什么要雇佣我们呢?

Monica wouldn't be so busy and stressed if she didn't have a finger in every pie.

如果不是莫妮卡每件事都想插手管一管的话，她就不会这么忙，压力这么大了。
