In a large bowl, mash avocados. Stir in sour cream. Gently fold in tomatoes, jalapeños, garlic, onion, cilantro and lime juice.
Season to taste with salt and pepper. Serve immediately.
Notes
~Short on prep time, substitute 1/2cup (125mL) of your favorite salsa or fresh pico de gallo for the tomatoes, jalapeños, garlic, red onion and cilantro.~I enjoy making and serving guacamole in a molcajete, the traditional Mexican version of a mortar and pestle.~Substitute non-fat, plain Greek yogurt for the sour cream if preferred. ~For added flavor, season to taste with chili powder, or cumin.
