Cut the avocados in half, remove the pit, and scoop the flesh into a mixing bowl.
Using a fork, mash the avocados to your desired consistency. Some prefer it chunky, while others like it smooth.
Add the lime juice and salt to the mashed avocados.
Stir in the diced onion, chopped cilantro, diced tomatoes, and minced garlic.
If you like a bit of heat, add a pinch of ground cayenne pepper to the mixture.
Mix all the ingredients together until well combined.
Enjoy your meal!
