我会做很好吃的饭

you should say "我很会做饭，并且饭做得很好吃“ they are actually two sentences. you need to pause between each sentence or you should add a logical word to connect them. so it would be translated literally as " I’m good at cook and i cook well"

要停顿一下，用逗号分开表达。 我很会做饭，我做的饭很好吃。 也可以这样表达：我厨艺很好。

你可以说我很会做饭，并且做的很好吃

Thanks so much
