However, it's important to note that the exact meaning might be slightly different depending on the context. Here are some possible variations:
* "What I told you!" (with emphasis, indicating that the speaker is reminding the listener of something important)
* "As I told you..." (introducing a statement that confirms what was previously said)
* "You know what I told you..." (assuming that the listener remembers the information)
It's also worth mentioning that "que yo te dije" can be used in a more informal way, especially in spoken Spanish. In that case, it might be closer to "what I said" or "like I told you".
To understand the exact meaning of "que yo te dije", it's important to consider the full context of the conversation and the tone of voice used.
