Start by slicing the avocados in half, removing the pits, and scooping the flesh into a mixing bowl. Use a fork or potato masher to mash the avocados to your preferred level of creaminess.
Once your avocados are mashed, add in the drained canned tomatoes, finely chopped onion, and minced garlic. Stir gently to combine.
Pour in the bottled hot sauce, vegetable oil, lemon juice, and sprinkle the salt over the mixture. Stir well to evenly distribute all the ingredients. Taste and adjust the seasoning if necessary.
Let your El Fenix Guacamole sit for about 30 minutes in the refrigerator before serving to allow the flavors to develop and intensify.
