Drain the heart of palm can and slice the hearts into 1/4 inch pieces.
In a large bowl, combine the sliced hearts of palm, chopped tomatoes, and sliced red onion.
Add in the chopped avocado and mix gently to avoid smashing the avocado pieces.
In a small bowl, combine the lime juice and minced garlic, stirring until well mixed.
Pour this lime-garlic dressing over the salad ingredients in the large bowl.
Toss everything together gently to ensure all the ingredients are evenly coated in the dressing.
Season the salad with salt to your liking.
Allow the salad to rest for a few minutes to let the flavors meld together, then serve
