-Avocado
-Lime juice to taste
-Salt to taste
-Cilantro to taste, finely chopped (Skip if you don't have, but makes it a lot better)

Basically just combine everything. A good starting point if you're not sure on ratios would be
-2 avocados
-Half a lime
-Sprinkle of salt
-tbsp to 1/4 cup cilantro

Pro tip: DO NOT over mix or over smash the avocado. If you do, it'll come out too smooth and creamy, it won't be right. Only stir as little as needed.
