For Katie Lee's quick homemade guacamole, put 2 pitted and peeled avocados into a mixing bowl and mash them with a fork until chunky. Add 2 cloves of minced garlic, 1 minced serrano chile, 1 tablespoon of lime juice and 2 tablespoons of chopped fresh cilantro leaves. Mix well until combined and season with kosher salt and freshly ground black pepper.
