Start by dicing the tomatoes, chopping the onion, and finely chopping the jalapeño (if using). Make sure to remove the seeds from the tomatoes and jalapeño.
2 pcs tomatoes, 1/2 pcs red onion, 1 pcs jalapeño
In a medium bowl, mix the tomatoes, onions, and jalapeño (if using). Add the chopped cilantro and season with salt and pepper to taste.
1/2 cup fresh cilantro, Salt and pepper
Gently fold in the diced avocado; you want to make a chunky salsa, not to mash it.
1 pcs avocado
Squeeze the lime juice and olive oil over the mixture.
1 pcs lime, 1 tablespoon olive oil
Notes
Enjoy immediately as a dip with tortilla chips, a topping for tacos, or as a refreshing side salad.
