Dice the celery and do the same as with the tomato, but only integrate it after chopping the serrano pepper if you're using it. Otherwise, let it rest for about 3 minutes, then mix everything. Add the soy sauce to give the dish flavor, let it rest a bit without turning off the stove, stirring occasionally. Finally, add the Maggi seasoning and mix. Let it cook until the celery is well cooked, ensuring the dish doesn't dry out, then set aside.

In another clean and dry pan, add the remaining oil, heat it, and lightly fry the tortillas until they soften. Before they are fully fried, make quesadillas with the previous filling. The cheese you use should melt well to seal the contents with the cheese. Brown your quesadillas well on both sides. If you like, you can fry one or more peppers and add a bit of soy sauce and Maggi seasoning.
