This vegan hearts of palm ceviche will transport you to Mexico with the combination of habanero, lime juice, tomato, onion and hearts of palm
You might have to try several brands of hearts of palm and see which one you like best. Some are more tender than others. The recipe calls for 1 whole habanero, but if you don't eat a lot of spicy food I would add 1/2 or even a 1/3 of a pepper. Oil is optional. Avocado would go really well with this.
