While not all kids may like a tomato-based salsa, I find that most enjoy this one. It is light on spice but has a sweet and tangy flavor. Even if they don’t want to add it to their tacos, they can eat it plain with tortilla chips. There is almost never any of this salsa left when I serve it at our parties. This is also wonderful served on top of grilled pork or chicken.
Add pineapple, cilantro, onion, and serrano pepper to a large bowl. Toss gently to combine. Add the zest and juice of the limes and the salt. Cover and chill until ready to use. Right before serving, add the diced avocado and toss to combine.
