I’m so hungry, I really want to eat grilled fish. How to say it in Cantonese?

Let me tell you first. What do ordinary people in Cantonese say? The grammar of this sentence is? I am so hungry, as if I was eating grilled fish? The pronunciation is "head monkey oh, monkey bear se hao" (the first sound) "fish" or very hungry, like eating grilled fish, the pronunciation is "Hericium oh, Xiong sehao fish"

Hungry → Oh, when you pronounce this oh, press the back of your tongue upwards, and then pronounce it. ?That’s what it feels like.

Se → Actually I don’t pronounce se, I just found a random word to replace it. Please note that the pronunciation is six? In English, don’t pronounce si~ the ending sound, it is six? If there is no pronunciation of s ending sound, you Give it a try?. I’m so tired. Where can I tell you?

By the way, can you tell me something about it? I am pronunciating it in Cantonese. Some people like to read the pronunciation I just said, and some people like to use the first sound of oh~. The tongue does not move upward, but it is a personal feeling. It still sounds like the pronunciation I said.
