Begin by washing the clementine oranges. Peel and segment them, removing any seeds. Chop the segments into bite-sized pieces and set them aside.
Cut the avocados in half, remove the pit, and scoop the flesh out into a mixing bowl. Dice the avocado into small cubes, being careful not to mash them too much.
Finely dice the red onion and jalapeño. If you prefer a milder salsa, be sure to remove the ribs and seeds from the jalapeño before dicing.
In the bowl with the diced avocado, add the chopped clementines, red onion, jalapeño, and cilantro.
Drizzle the olive oil and lime juice over the mixture. Sprinkle with salt and pepper. Gently stir everything together, being careful not to mash the avocado too much.
Give your salsa a taste! Adjust the seasoning with more salt, lime juice, or jalapeño if desired.
Allow the salsa to chill in the refrigerator for at least 30 minutes to let the flavors meld. Serve with tortilla chips for a delicious snack or appetizer.
