Start by cutting the avocados in half, removing the pit, and scooping the flesh into a mixing bowl. Use a fork or potato masher to mash the avocados to your preferred level of creaminess.
Add the drained and coarsely chopped canned tomatoes to the mashed avocados. Next, stir in the bottled hot sauce, vegetable oil, finely chopped onion, salt, fresh lemon juice, and minced garlic.
Using a spatula or spoon, gently mix all the ingredients together until well combined. Be careful not to overmix; you want to maintain some texture while ensuring everything is evenly distributed.
Taste the guacamole and adjust the seasoning as needed. If you prefer it spicier, feel free to add more hot sauce or minced garlic. If it needs a little more brightness, a dash more lemon juice can do the trick.
Transfer your El Fenix Guacamole to a serving dish. Pair it with crispy tortilla chips, fresh veggies, or use it as a delicious topping for your favorite Mexican dishes.
