Cut tomato into small cubes, finely chop red onion and cilantro. Remove the seeds and core from the chili pepper and finely chop.
Place all ingredients in a small bowl, toss well, and season to taste with salt and pepper.
Notes
Chili: The authentic Mexican recipe uses green jalapeños. Unfortunately, in some countries, these are hard to find and can therefore be replaced by green or red chilies. 🌶 Store leftovers for up to 2 days in a sealed container in the refrigerator.Delicious with tacos, quesadillas, or nachos.
