- Place the avocados in a large glass bowl and mash with the back of a fork. Stir in the jalapeno, red onion, cilantro, garlic, lime zest and juice, salt and black pepper until combined. Cover and refrigerate at least 30 minutes. Stir, then taste and adjust seasoning, if necessary.
- Top with diced peaches and serve immediately with tortilla chips.
Storage Tip: If you’re making the guacamole ahead of time, pour a thin layer of water on top of the guacamole, cover and refrigerate. When you’re ready to serve, pour off the water and stir before placing the peaches on top. This helps avoid the oxygenation (browning) of the avocados.
